Description

The present invention relates to a supply roll with at least one spacer and a method for handling such a supply roll.

Such stock rolls can be used for example in the field of packing technology. Apparatuses are known which provide uninterrupted flat and / or strip material in order to wrap articles with the flat and / or strip material and to combine them in this case. For example, the flat and / or strip material may be formed as a shrink film, wherein a plurality of beverage containers are wrapped by means of the shrink film and combined into containers.

If the supply of flat and / or strip material of a roll is exhausted, the roll must be replaced by another roll with new flat and / or strip material in order to continue a packaging process and preferably to perform uninterrupted.

Devices for an uninterrupted packing process as well as corresponding supply rolls, which can be used for an uninterrupted packing process, are known for example from US Pat DE 195 22 110 A1 known. In the device known from DE-application two parallel shafts are provided, sit on which supply rolls. From the supply rolls shrink film is unwound and placed around articles. The articles then pass through a shrink tunnel. If the stock of shrink film of a roll is exhausted, then shrink film of another roll is connected to the strip supply of the first roll by means of welding.

If the shrink films of two rolls are to be joined by means of welding, a free end region of a new roll is first to be removed from this and, for the purpose of welding, to be moved in the direction of the further roll. Frequently, the position of the free end portion is unknown, so that the new role must first be manually rotated or oriented, whereupon the free end portion is moved in the direction of the other role, to weld this with shrink film of the other role.

Practice has shown that when removing a free end portion of a supply roll, an external layer can adhere to an adjacent layer, which is accompanied by problems in the removal of flat strip material. For example, due to an electrostatic adhesion, an outer layer may adhere to its directly adjacent layer, so that the outer layer can not be removed in a targeted manner. It is also conceivable that an outer layer and a layer adjacent to the outer layer are mechanically wedged or hooked, so that an outer layer can not be pulled off the supply roll without problems associated therewith.

In other conceivable devices, external layers are detected pneumatically and by negative pressure. It may be that several adjacent layers are unintentionally received together, which is accompanied by problems when removing flat and / or strip material. In particular, in supply rolls, on which flat and / or strip material is added with low strength, such problems may arise in practice.

For automated or semi-automated processes, it would be desirable to have supply rolls or processes which at least partially avoid or reduce such problems when replacing supply rolls.

An object of the invention can therefore be seen to provide a supply roll and a corresponding method for dealing with such supply rolls available, by means of which problems when removing flat strip material can be at least reduced. The supply roll should also have a simple structure. The process should be easy to implement.

The above objects are achieved by a supply roll and by a method for handling supply rolls, which comprise the features in the claims 1, and 14. Further advantageous embodiments are described by the subclaims.

The supply roll has a roll core, which may be hollow cylindrical and may be formed by cellulose or plastic. Furthermore, the supply roll comprises flat and / or strip material which is carried by the roll core with a multiplicity of windings. The flat and / or strip material may be formed for example by shrink film or stretch film.

Next at least one spacer is part of the supply roll according to the invention. The at least one spacer is interposed between a free end regions of the flat and / or strip material and a layer adjacent the free end region of the flat and / or strip material such that a certain distance between the free end region and the free end region via the at least one spacer neighboring Location of the flat and / or strip material is made.

For example, at least one spacer can be designed as an adhesive bond or adhesive point, which adhesive bond or adhesive dot is located between the free end region and the layer adjacent to the free end region. The adhesive bond or the adhesive point can adhere to the free end region and / or at the position adjacent to the free end region.

In conceivable embodiments, the at least one spacer may extend at least partially or completely over the entire depth of the supply roll, but not project laterally from the supply roll or from the flat and / or strip material.

In preferred embodiments, the supply roll may have at least one contact region formed in the circumferential direction of the supply roll for a take-off means designed to remove flat and / or strip material. The at least one contact region may be optically recognizable and / or optically detectable on the supply roll and may be formed in the region of the at least one spacer and / or on at least one spacer in the circumferential direction of the supply roll.

For the design of the trigger means, as it is also part of the method described below, numerous possibilities are conceivable. For example, the extraction means may be formed as a pneumatic suction and / or gripping device. In addition, embodiments are conceivable in which the withdrawal means is designed as a magnetic rod, which optionally enters into contact with a metal foil and / or coating fixed to the free end region, in order to receive or grasp the free end region. Also, withdrawal means are conceivable in which the free end region is positively received or clamped. For example, the extraction means for this purpose have at least one rotating roller, by means of which the free end region can be positively detected. Also, the free end region of the flat and / or strip material form a hook, which occurs with a corresponding and formed as part of the withdrawal means counter hooks in conjunction to deduct flat and / or strip material from the supply roll.

Furthermore, it may be that the supply roll comprises at least one functional mark, by means of which at least one formed in the circumferential course of the supply roll contact area for the trigger means is recognizable and / or detectable. The at least one functional marking may be formed at a specific position in the free end region of the flat and / or strip material, so that information about the relative position of the free end region can be visually recognized via the at least one functional marking and the respective at least one contact region, which may be has a certain orientation or relative position relative to the free end region, can be determined. In further embodiments, the at least one function marking may have a symbolism and / or an optical reference which directly refers to the at least one contact region. To implement the method according to the invention, if necessary, a sensor system can be provided which detects the position of the at least one function marking and optionally applies the extraction means to the at least one contact area in order to receive the free end region of the flat and / or strip material.

It is also conceivable that the at least one functional mark consists of a print job, which is applied in defined relative position to at least one contact area on the flat and / or strip material. The print job may comprise, for example, a mark formed as a line which extends parallel to a terminal edge of the outer free end region of the flat and / or strip material. Accordingly, at least one functional marking in the region of a free end or in the free end region can be introduced into the flat and / or strip material and / or applied to the flat and / or strip material.

It may also be that the at least one spacer itself forms the at least one contact region or that the at least one spacer itself is formed as the at least one contact region.

In addition, embodiments in which the at least one spacer has, at least in some areas, a rigidity which is designed to be larger than the rigidity of the flat and / or strip material, have proved to be useful.

For example, the at least one spacer made of cellulose or cardboard can be formed. In conceivable further embodiments, the at least one spacer can be made of plastic and, if appropriate, have the rigidity just described at least in regions, which is designed to be larger than the rigidity of the flat and / or strip material.

In addition, it may be that the at least one spacer has two opposite broad side surfaces with a respective adhesive bond, via which adhesive bonds the at least one spacer the free end region of the flat and / or strip material at the free end region adjacent position of the flat and / or strip material sets. For example, it may thus be that the at least one spacer is designed as a band or double-sided adhesive tape with a respective adhesive bond on opposite broad side surfaces.

The at least one spacer can be arranged in sections between the free end region of the flat and / or strip material and the layer adjacent to the free end region so that a portion of the at least one spacer with an external adhesive connection projects beyond a terminal edge of the flat and / or strip material , At least one and preferably two opposite broad side surfaces of the at least one spacer can each have an adhesive connection, by means of which the at least one spacer is fixed to the free end region and / or to the position adjacent to the free end region. By way of the at least one spacer, which is thus possibly designed as a double-sided adhesive tape, the free end region can thus be fixed to the layer adjacent to the free end region until the free end region, as described below, is withdrawn from the supply roll. In conceivable embodiments, it may be sufficient if a broadside surface of the at least one spacer has an adhesive bond, over which the at least one spacer or optionally the adhesive tape is fixed at the free end region.

In addition, it can be provided that the at least one spacer is connected to the free end region via a first adhesive bond and via a second adhesive bond to the layer adjacent to the free end region, wherein the first adhesive bond has a greater adhesive force than the second adhesive bond. If the free end region of the flat and / or strip material is pulled off, the adhesive bond formed between the at least one spacer and the free end region can be retained, whereas the adhesive bond formed between the at least one spacer and the layer adjacent to the free end region is canceled.

Further, the supply roll may comprise at least one adhesive label which rests on the outside of the free end region of the flat and / or strip material. In this case, between the at least one adhesive label and the free end region of the flat and / or strip material and between the at least one adhesive label and the free end region adjacent layer of the flat and / or strip material in each case an adhesive bond is formed to the free end region of the flat - And / or strip material at the free end region adjacent position of the flat and / or strip material set. The at least one adhesive label can form the at least one contact region.

For example, the at least one adhesive label may be fixed to a broadside surface facing away from the roll core of an outer layer of the flat and / or strip material. Advantageously, the free end region can retain its relative position on the supply roll through the adhesive bond or through the at least one adhesive label. The risk of unintentional unwinding of flat and / or strip material from the supply roll is thereby reduced. The adhesive bond formed between the free end region and the at least one adhesive label may have a lower adhesive force than the adhesive bond formed between the at least one adhesive label and the layer adjacent the free end region. If the free end region is then removed from the supply roll, the at least one adhesive label can continue to be in communication with the free end region, whereas the adhesive bond formed between the at least one adhesive label and the layer adjacent to the free end region is removed when the free end region is removed. In particular, such embodiments have proven useful provided that at least one adhesive label forms the at least one contact region. The free end region can then be removed via the at least one adhesive label, whereby the adhesive bond formed between the at least one adhesive label and the layer adjacent to the free end region is removed.

Also, the at least one adhesive label in the direction of the free end region adjacent to taper point and possibly have two opposing triangular broad side surfaces. Of the two opposite triangular broad side surfaces which abut the supply roll broadside surface may be formed as an adhesive surface. In this case, the free end region can advantageously be easily removed, whereby the connection between the layer adjacent to the free end region and the at least one adhesive label is released and the connection between the at least one adhesive label and the free end region is maintained.

In conceivable embodiments, it may also be the case that the at least one functional marking previously described has been applied to the at least one adhesive label. The at least one adhesive label can therefore possibly refer to the at least one contact area.

It is also conceivable that the free end of the flat and / or strip material over at least one adhesive bond is fixed to the free end region adjacent layer of flat and / or strip material.

Furthermore, preferably at least one perforation can be introduced into an outer layer of the flat and / or strip material in the free end region or in the area of the free end of the flat and / or strip material. The at least one perforation can in this case extend completely over the entire width or depth of the flat and / or strip material.

The at least one perforation can be arranged downstream of the at least one contact region in a winding direction of the flat and / or strip material. In addition, the at least one perforation of the at least one adhesive bond may be arranged upstream in the direction of winding of the flat and / or strip material. The at least one adhesive bond may, as previously described, be formed by at least one adhesive label and / or introduced into the supply roll between the free end region and a position of the flat and / or strip material adjacent to the free end region.

In particularly preferred embodiments, at least one spacer may be formed as a spacer spring with at least two legs, which spacer spring at least partially between at least two legs between the free end region of the flat and / or strip material and the free end region adjacent position of the flat and / or Band material is positioned.

Also, at least one spacer or optionally at least one further spacer may be formed as a spacer spring with at least two legs, which spacer spring engages with its at least two legs a terminal edge of the flat and / or strip material. For the sake of completeness, it should be mentioned that embodiments are conceivable in which at least one distance spring with its at least two legs is positioned between an outer layer of the flat and / or strip material and the layer of flat and / or strip material adjacent to the at least one contact region is and at least one further distance spring with its at least two legs surrounds a terminal edge of the flat and / or strip material.

A first leg of the spacer spring can be connected via a first adhesive connection with the free end region of the flat and / or strip material. Further, a second leg of the spacer spring via a second adhesive bond with the free end region adjacent position of the flat and / or strip material are in communication. The spacer spring may be formed integrally with the first leg and the second leg.

In various embodiments, the second adhesive bond may have a lower adhesive force than the first adhesive bond. If flat and / or strip material or a free end region of the flat and / or strip material is withdrawn from a supply roll, the distance spring can adhere via its second leg to the free end region of the flat and / or strip material, whereas the adhesive bond between the first leg and the position of the flat and / or strip material adjacent to the free end region is released when the free end region is removed.

It may further be the case that the first leg and the second leg are connected to one another via a third adhesive connection, which third adhesive connection has a lower adhesive force in relation to the first adhesive connection and in relation to the second adhesive connection.

Further, a lot of the spacer spring may have an external adhesive connection. On the external adhesive connection, a trigger means, as described below, put on to deduct the free end portion of the supply roll.

The invention further relates to a method for handling a previously described supply roll. Features which have been mentioned above can thus also be used to carry out the method described below. In addition, features which will be described below may be provided for various embodiments of a supply roll according to the invention.

As part of the process, the supply roll is inserted into an installation position of a packaging machine. In the installation position, a mandrel or retaining mandrel may be provided on which the supply roll is pushed upon insertion into the installation position. The mandrel or retaining mandrel can fix the supply roll hereupon clamp.

After the supply roll has been inserted into the installation position, a withdrawal means, for example a rod or a pneumatic suction head, is placed on the supply roll in the circumferential direction and in the region of the at least one spacer.

Subsequently, a detachable connection between the withdrawal means and the free end region of the flat and / or strip material is produced. The detachable connection does not have to be mandatory here be made directly between the take-off and the flat and / or strip material. As already mentioned, it may be that at least one spacer and / or at least one adhesive label are fixed at the free end region. The releasable connection can therefore be made between the withdrawal means and the at least one spacer and / or between the withdrawal means and the at least one adhesive label. In further embodiments, however, it is also conceivable that the withdrawal means touches directly on the flat and / or strip material. In particular, the extraction means can be designed for this purpose as a pneumatic suction and / or gripping device.

Following this time, the withdrawal means is moved in the direction away from the supply roll, wherein the releasable connection remains formed and as a result of which flat and / or strip material is unwound from the supply roll.

As already described, a lot of the at least one spacer with an external adhesive connection can project beyond a terminal edge of the flat and / or strip material. Within the scope of conceivable embodiments of the method according to the invention, the take-off means can hit the outer adhesive bond when placed on it and, as a result, bind to the at least one spacer. The withdrawal means may be formed, for example, as a rod which rests on the external adhesive bond. When moving the trigger in the direction away from the supply roll, between the free end region adjacent layer and the at least one spacer formed adhesive bond can be solved, whereas formed between the at least one spacer and the free end region of the flat and / or strip material adhesive bond and the Binding of the at least one spacer to the trigger to be preserved.

In a conceivable embodiment of the method can also be provided that the previously described perforation of the supply roll is broken in a movement of the at least one suction and / or gripping device in the direction away from the supply roll and the free end region of the flat and / or strip material during movement the at least one suction and / or gripping device remains fixed on the layer adjacent to the at least one contact region via the adhesive connection.

It can also be provided in the context of the method that the at least one contact region is completely formed by the at least one adhesive label, resulting from a movement of the trigger element in the direction of the supply roll resulting adhesive bond, which between the at least one adhesive label and the free end region adjacent Able to be trained, is canceled. In addition, from a movement of the trigger element resulting adhesive bond, which is formed between the at least one adhesive label and the free end portion of the flat and / or strip material, remain so that the at least one adhesive label together with the free end of the withdrawal means of the Stock roll is deducted.

In addition, embodiments for the method according to the invention are conceivable in which at least one spacer is designed as a previously described spacing spring. From a movement of the at least one suction and / or gripping device in the direction of the supply roll resulting, the second adhesive bond can be solved, so that the distance spring is no longer in communication with the free end region adjacent position of the flat and / or strip material. In addition, the first adhesive connection may remain in the movement of the at least one trigger element, so that the spacer spring is withdrawn together with the free end region of the flat and / or strip material from the supply roll.

In further embodiments, the supply roll, as already mentioned, have a third adhesive connection, by means of which the first leg and the second leg of the spacer spring are in communication with each other. Within the scope of a conceivable embodiment of the method according to the invention, it can be provided that the third adhesive bond is released as a result of a movement of the at least one suction and / or gripping device in the direction of the supply roll, so that the first leg and the second leg no longer have contact the third adhesive joint communicate with each other.

For identical or equivalent elements of the invention, identical reference numerals are used. Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures, which are required for the description of the respective figure. The illustrated embodiments are merely examples of how the invention may be configured and are not an exhaustive limitation.

1 show a schematic exploded view and a schematic frontal view of a first embodiment of a supply roll according to the invention 1 , So is in 1A the schematic exploded view of the embodiment of a supply roll 1 shown while 1B the supply roll 1 out 1A shows from the front.

The supply roll 1 includes a roll core 3 which is hollow cylindrical and made of plastic or cellulose. On the roll core 3 sits flat and / or strip material 5 with a variety of windings on and off the roll core 3 carried. Next are several function marks 7 to recognize that in the area of a trailing edge 12 of the flat and / or strip material 5 in a defined relative position on the supply roll 1 seated. In practice, for example, a patent application in the figures can not be provided with the optical detection device shown, which the function marks 7 or the positions of the function marks 7 visually recognizes. Taking into account the recognized positions, this can be deducted 50 and, for example, a suction and / or gripping device (see. 6 and 8th ), as described below, are controlled.

Shown are also contact areas 6 on which the withdrawal means 50 (see. 6 and 8th ). The contact areas 6 each have a certain orientation and spacing from the function marks 7 , so that after an optical detection of the function marks 7 the contact area 6 can be determined.

The function marks 7 be in 1 each with an adhesive label 8th trained and stand over an adhesive connection with the free one end 10 of the flat and / or strip material 5 as well as with one of the contact areas 6 lying or the contact areas 6 and the free end area 10 neighboring location 14 of the flat and / or strip material 5 in connection. Here are the function marks 7 or adhesive labels 8th over the trailing edge 12 of the flat and / or strip material 5 guided and set the free end area 10 of the flat and / or strip material 5 at the free end area 10 neighboring location 14 firmly.

Further possess adhesive labels 8th a triangular geometry, allowing the adhesive between the adhesive label 8th and the contact areas 6 neighboring location 14 a lower adhesive force than the adhesive between the adhesive label 8th and the free end area 10 of the flat and / or strip material 5 has.

If flat and / or strip material 5 via a deduction agent 50 at the contact area 6 is detected and removed, the adhesive bond between the adhesive labels 8th and the location 14 , which is the free end area 1ß adjacent, whereas the respective adhesive bond between the adhesive labels 8th and the free end area 10 preserved. The adhesive label 8th thus becomes together with the free end area 10 subtracted or remains at the free end 10 be liable.

The exploded view 1A also leaves a spacer 9 recognize which the free end area 10 of the flat and / or strip material 5 and the free end area 10 neighboring location 14 on flat and / or strip material 5 is interposed such that on the spacer 9 a certain distance between the free end area 10 and the free end area 10 neighboring location 14 of the flat and / or strip material 5 will be produced. Due to the distance is the free end 10 of the flat and / or strip material 5 at least in the vicinity of the contact areas 6 not with the free end area 10 neighboring location 14 of the flat and / or strip material 5 in surface contact.

The present is the spacer 9 formed by cellulose. For further embodiments, however, it is also conceivable that the spacer 9 as double-sided adhesive tape or possibly not adhering and formed by plastic.

Because the adhesive labels 8th the free end area 10 at the free end area 10 neighboring location 14 of the flat and / or strip material 5 fix, is the spacer 9 clamped between the free end area 10 and the contact areas 6 neighboring location 14 of the flat and / or strip material 5 held.

The arrow in 1A also refers to a winding direction WR for the flat and / or strip material 5 , A synopsis of 1A and 1B clarifies here that the contact areas 6 the adhesive labels 8th and the trailing edge 12 of the flat and / or strip material 5 are arranged upstream in the winding direction WR.

1B also shows that the spacer 9 below the free end area 10 located and at least approximately over the entire depth of the supply roll 1e or the flat and / or strip material 5 in the free end area 10 extends.

2 shows a schematic partial view of the embodiment of a supply roll 1 out 1 with clarification of other aspects. So are in 2 again the free end area 10 of the flat and / or strip material 5 , the adhesive label 8th as well as the spacer 9 to recognize. The the free end area 10 neighboring location 14 of the flat and / or strip material 5 is in 2 not shown.

As in 2 to recognize, stands the spacer 9 flat with the flat and / or strip material 5 or with the free end area 10 of the flat and / or strip material 5 in surface contact. This will provide an optimized spacing between the free end region 10 and the free end area 10 neighboring location 14 of the flat and / or strip material 5 reached. If a deduction 50 Flat and / or strip material 5 at the contact areas 6 if necessary detected pneumatically, which is the free end 10 neighboring location 14 due to the over the spacer 9 produced spacing not included.

3 shows a schematic perspective view of another second embodiment of a supply roll according to the invention 1 , The supply roll 1 of the embodiment 3 still has several adhesive labels 8th , which feature marks 7 form. There are also several contact areas 6 provided on which for stripping flat and / or strip material 5 a deduction agent 50 touches down. The flat and / or strip material 5 is from a roll core 3 carried. digit 14 continues to point to the free end area 10 neighboring location 14 of the flat and / or strip material 5 , The adhesive labels 8th put the free end area 10 of the flat and / or strip material 5 via an adhesive connection at the free end area 10 neighboring location 14 firmly.

The spacer 9 is in 3 however, it is not located between the free end area 10 and the free end area 10 neighboring location 14 of the flat and / or strip material 5 , An embodiment and position for the spacer 9 the supply roll 1 out 3 Therefore, according to the embodiment of a supply roll 1 from the 1 and 2 respectively.

In the free end area 10 is in the flat and / or strip material 5 a perforation 16 brought in. The perforation 16 is the contact areas 6 in the winding direction WR of the flat and / or strip material 5 downstream and the adhesive labels 8th or via the adhesive labels 8th trained adhesive bonds in the winding direction WR of the flat and / or strip material 5 upstream.

If a deduction 50 or optionally a suction and / or gripping device flat and / or strip material 5 at the contact areas 6 pneumatically detected and moving in the direction of the supply roll 1 moves, the perforation becomes 16 broken, whereas those between the free end area 10 and the adhesive labels 8th as well as between the free end area 10 neighboring location 14 and the adhesive labels 8th trained adhesive bond is maintained. Will be flat strip material 5 further from the supply roll 1 unwound, are the adhesive labels 8th continue at the free end area 10 neighboring location 14 of the flat and / or strip material 5 fixed.

One between the adhesive labels 8th and the free end area 10 as well as the location 14 trained adhesive force is therefore increased in relation to a force which breaks the perforation 16 is needed.

4 shows a schematic perspective view of another third embodiment of a supply roll according to the invention 1 , Also the supply roll 1 from the embodiment 4 has several adhesive labels 8th , which feature marks 7 form. About the function marks 7 can the multiple contact areas 6 be determined, on which a withdrawal means 50 and optionally a suction and / or gripping device (see. 6 and 8th ) can put on.

The supply roll 1 has a roll core 3 which the flat and / or strip material 5 wearing. The adhesive labels 8th put the free end area 10 of the flat and / or strip material 5 via an adhesive connection at the free end area 10 neighboring location 14 of the flat and / or strip material 5 firmly.

The supply roll 1 out 4 also has a spacer 9 which is in 4 can not be seen and as shown 6 or the embodiment of 1 can be trained. For the design and position of the spacer 9 is therefore on 1 respectively. 6 directed. 4 lets you know that the contact areas 6 completely through the adhesive labels 8th be formed. A deduction agent 50 can therefore on the contact areas 6 put on and the adhesive labels 8th fix via vacuum. Will the trigger 50 then in the direction of the supply roll 1 moves, which dissolves between the adhesive labels 8th and the free end area 10 neighboring location 14 trained adhesive bond, whereas one between the adhesive labels 8th and the free end area 10 or the outer layer of the flat and / or strip material 5 trained adhesive bond remains. The free end area 10 of the flat and / or strip material 5 is therefore together with the adhesive labels 8th while repealing the situation between 14 and the adhesive labels 8th withdrawn trained adhesive bond.

5 shows a schematic perspective view of a further fourth embodiment of a supply roll according to the invention 1 , Also the supply roll 1 out 5 owns flat and / or strip material 5 , which comes with a variety of windings from a roll core 3 will be carried. The embodiment of 5 has a self-adhesive label 8th , which is approximately over the entire depth or width of the supply roll 1 extends. A contact area 6 gets completely through the adhesive label 8th formed or is completely on the adhesive label 8th positioned. The adhesive label 8th connects the free end area 10 of the flat and / or strip material 5 and the free end area 10 neighboring location 14 of the flat and / or strip material 5 by adhesive bond.

The supply roll 1 out 5 also has a spacer 9 , which as shown in 1 or 6 can be trained and in 5 can not be seen. For the design and position of the spacer 9 is therefore on 1 respectively. 6 directed.

If a deduction 50 on the contact area 6 or on the adhesive label 8th touch down and temporal on it in the direction of the supply roll 1 is moved between the adhesive label 8th and the free end area 10 neighboring location 14 trained adhesive bond, whereas the adhesive bond between the adhesive label 8th and the free end area 10 preserved. The adhesive label 8th thus becomes together with the free end area 10 via a deduction agent 50 deducted.

6 illustrates the implementation of a conceivable embodiment of a method according to the invention with a supply roll 1 according to the embodiment 4 or 5 ,

In 6 is now the trigger 50 to recognize, which is presently designed as a suction and / or gripping device and which on the contact area 6 can be placed to present the adhesive label 8th to fix via vacuum and flat and / or strip material 5 from the supply roll 1 deducted.

The adhesive label 8th is about an adhesive application 17 with the free end area 10 as well as in 4 and 5 shown, the flat and / or strip material 5 in connection. In addition, the spacer 9 to recognize which the adhesive label 8th or the contact area 6 opposite one in 6 not shown and the free end 10 neighboring location 14 (see. 4 and 5 ) of the flat and / or strip material 5 spaced.
