Definitions

  • This invention relates to a method for painting and a device for carrying out the method, in accordance with the preamble of the following claim 1.
  • the invention is preferably intended to be used in connection with re- spraying of vehicles.
  • Masking means that certain parts are covered in an appropriate manner, e.g. paper which is fastened by tape, so that the paint cloud, which is to be applied, cannot come into contact with these masked parts.
  • an appropriate manner e.g. paper which is fastened by tape
  • the paint cloud which is to be applied
  • the known masking is made in such a manner that masking tape is used in order to fasten for example a piece of sheet-like paper, which has a form adopted to the geomet ⁇ ry of that part which is to be protected.
  • Such masking is time-consuming and does not always to ⁇ tally prevent the paint cloud from reaching one of the surfaces.
  • a further problem in connection with this known technique is that the tape leads to the creation of an edge. This edge is very difficult to eliminate. Accordingly, it is possible to ascertain if a car has been repainted or not by means of said edge. Since repainted cars have a lower second-hand value than non-repainted cars, this is not desirable.
  • the object of the invention is to achieve a method and a device for carrying out the method, which eliminates the mentioned disadvantages that are to be found in connec ⁇ tion with known methods and devices.
  • Fig. 1 shows a side-view of a car which has the device of the invention applied to it
  • Fig. 2 shows a section, a chosen part of a car in accordance with Fig. 1
  • Fig. 3 shows a device for storage of a device in accor ⁇ dance with the invention.
  • Fig. 4 is a sectional view of a device according to claim 3,
  • Fig. 5 is an alternative to the storage means, and, Fig. 6, 7, 8, 9 show different alternative configu ⁇ rations of transversal sections of a device in accordance with the invention.
  • Fig. 10 shows the fitting of an alternative embodiment in a gap of a car door, when the door is open, and.
  • Fig. 11 shows a device in accordance with Fig. 10 when the door is closed.
  • Fig. 1 there is shown a car, which before being re- sprayed, has been provided with a masking device 1 in accord-ance with the invention.
  • the masking device 1 which preferably is made of a foam rubber, is applied in an outer transition area along the whole length of the gap, which is formed between the two adjacent parts 3,4, which are to be painted.
  • one of these parts is a door 3 and the other one that part 4 which surrounds the door 3.
  • other areas, such as the boot and the bonnet, which comprise similar gaps have also been provided with a masking device 1 in accordance with the above.
  • Fig. 2 there is shown a section through a part of a car which is shown in Fig. 1.
  • the masking device 1 is applied to that part 4 which delimits said gap.
  • the attachment of the device 1 is preferably performed by means of an adhesive tape 2.
  • the masking device 1 is com ⁇ pressible and, preferably, also resilient.
  • the figure shows a part of a door 3 and a part of its interconnecting wall 31 which interconnects the inner skin 32 with the outer skin 30.
  • the outwardly facing sur ⁇ face of said intermediate wall 31 is one of the parts which is intended to be protected from receiving paint particles during the respray.
  • Another such surface is the one belonging to another intermediate wall 41, which in ⁇ terconnects the outer plate 40 and the inner plate 42 of the surrounding area.
  • the masking device 1 in accordance with the invention, prevents the paint cloud 8 from penetrating into the gap to reach the out ⁇ wardly facing parts of the intermediate walls 31 and 41 respectively: Due to the compressibility of the masking device, it presses against the surfaces 5,6 of the open ⁇ ing of the gap so that sufficient pressure is achieved in order to hinder the paint cloud 8. If the masking device 1 is also resilient, a continuous, smooth transition 5,6 can be achieved between the repainted surface and the old surface, especially if the masking device has an appro ⁇ priate form. An appropriate form means that the surface of the masking device is somewhat curved in that area where it meets the surface of the plate 5,6.
  • This curva ⁇ ture can be achieved partly by prefabricating the masking device with the curved outer surface or by providing an object (for example a door) , which moves the body so that the curvature of its outwardly facing surface is achieved, which in its turn creates said smooth transi ⁇ tion.
  • an object for example a door
  • Fig. 3 and 4 there is shown an appropriate manner of storing the invention.
  • the masking device 1 is hereby wound on the compression, in order to be space-saving. By winding it in such a manner that the adhesive part 2 is located along a common line, the one surface contacts the other layer so that it is compressed and that the wound masking device is kept in its wound state 4.
  • Fig. 4 shows in more detail how a sectioned device being wound-up in accordance with the invention looks.
  • Fig. 5 shows an alternative way of storing the device.
  • one stores the adhesive double-sided part 2 per se and the masking part 1 per se, preferably within one and the same container 9. When feeding it, both of these parts are arranged in such a manner that the double-sided adhesive part 2 is fed together with the masking device 1.
  • the container 9 is arranged with some appropriate means for cutting the device.
  • Fig. 6, 7, 8 and 9 show four different alternative forms which indicate possibilities concerning the creation of different embodiments within the scope of the invention.
  • the Fig. 6 shows the cylindrical embodiment which has been shown above. If one desires a larger contacting ad- hesive surface than this, it is appropriate to use an em ⁇ bodiment in accordance with Fig. 7 in which the size of the adhesive area has been enlarged.
  • a masking device with such a form can also have an adhesive surface of large size.
  • Fig. 10 there is shown a preferred embodiment of the invention used together with the car, where the body 1 has a triangular form and the adhesive tape 2 is attached to the base surface thereof.
  • the body 1 is attached to the side surface 41 of the B-post in such a manner that its outwardly exposed surface substantially in the same plane as the outer surface 40 which is to be painted.
  • the door 3 is shut (Fig. 11) , whereby the preferably elastic compressible body 1 is deformed in such a manner that a continuous smooth transition is achieved between the body 1 and the two contacting adja- cent areas 5,6 of the door 3 and B-post respectively.
  • the body with a bulb-like pro ⁇ truding part 11, which leads to large flexibility for the transition 6 between one surface 40, which is to be painted, and the other surface of the body 1, which is located adjacent to the adhesive part 2.
  • This embodiment has the advantage that one and the same body 1 can be used to seal mainly all different kinds of gaps with different dimensions, since the potential height of the seal is very large. Having a circular form, on trie other hand, may lead to problems in closing the door or to have the body 1 stay in the desired position.
  • foam-plastic has been mentioned above as a suitable mate ⁇ rial, but it is evident that all kinds of different mate- rials with similar properties may be used.
  • Any kind of fibre-based body is an example of an alternative materi ⁇ al, such as paper fibres. In such a case, however, the paper fibres need to have such a structure that they can counter-resist the pressure which is presented by the paint cloud 8.
  • Foam with a surface with adhesive qualities being pro ⁇ cuted in situ, is also possible to use.
  • a pressure con ⁇ tainer with an outlet from which said foam would be pro ⁇ quizd, is accordingly an alternative embodiment.

Abstract

L'invention concerne un procédé et un dispositif empêchant qu'un nuage de gouttelettes pulvérisées ne couvre certaines surfaces (31, 41) d'un objet à peindre de sorte que lesdites surfaces sont positionnées dans un plan différent par rapport aux surfaces de l'objet à peindre, un nuage de gouttelettes pulvérisées pouvant atteindre lesdites surfaces après passage dans un vide. Dans le passé, on a résolu ce problème en couvrant les surfaces (31, 41) à l'aide de feuilles lesquelles étaient fixées au moyen de ruban adhésif. L'invention résout ce problème d'une manière très simple, au moyen d'un corps (1) fixé de manière qu'il remplit le creux dans son intégralité, de manière que ledit nuage de gouttelettes pulvérisées (8) ne peut pas pénétrer dans ledit vide. Par conséquent, ledit nuage de gouttelettes pulvérisées ne peut pas couvrir lesdites surfaces (31, 41).
