Description
SPECIFICATION
Method of making patterned multi-laminar article
This invention relates to a method of simultaneously applying a pattern to a multi-laminar article and asembling the multi-laminar article.
In my U.K. Patent Specification No. 1572787 there is described and claimed a method for the application of motifs to textiles. The method comprises assembling a laminate, which has at least one layer of decorative material and a layer of hot-melt adhesive adhered thereto, with the textile to which a motif is to be applied. Heat is then applied to the assembly via a die which is shaped to correspond to the desired motif, whereby the hot-melt adhesive is activated in the peripheral regions of the motif in order to adhere the decorative material to the textile substrate in the peripheral regions. The die is then removed and the laminate is stripped from the substrate leaving only the motif defined by the die on the substrate.
It is often necessary to apply patterns to multilaminar articles such as shoe uppers. In this instance the shoe upper is normally assembled, and the pattern may be subsequently applied to the assembled shoe uppers in the way described above. This method is disadvantageous because two distinct process steps are required to make the finished shoe upper.
It is an object of the present invention to provide a method of assembling a multi-laminar article and simultaneously applying a pattern to the article.
According to the present invention there is provided a method of making a patterned multi-laminar article, said method comprising arranging an overlying layer, from which the pattern is formed, on an underlying multi-laminar material, said underlying material comprising at least a bottom layer and a top layer, with a lamina of an activatable adhesive between each pair of adjacent layers; applying pressure to said layers by means of a die which is shaped to correspond to the desired pattern; activating the lamina of adhesive adjacent the overlying layer is activated over at least part of the surface area of the pattern to be applied in order to adhere the part of the overlying layer corresponding to the pattern to the underlying material; activating the adhesive between the layers of the underlying material is activated in order to adhere the layers of the underlying material together; and thereafter removing part of the overlying layer from the underlying material whereby only the pattern defined by the die remains attached to the underlying material.
Advantageously the multi-laminar article is a shoe upper.
Preferably the bottom layer is a lining layer which comprises cotton or nylon, and the top layer is natural or synthetic leather. if desired the top layer may be natural suede leather, artifical suede leather, canvas, a coated or woven fabric, a polyurethane, polyvinyl chloride (PVC) or any other suitable material.
The overlying layer may be a plastics material, and is preferably a thermoplastics material, such as PVC.
It is preferable that the melting point of the overlying layer is less than that of the underlying material.
Materials such as flocked PVC, plain PVC and laminates manufactured from PVC can be used. It is preferred that the melting point overlying layer is in the range of 125"C to 175"C.
In a preferred embodiment an intermediate layer is provided between the top and bottom layers. The intermediate layer is preferably PVC, more preferably a foam PVC and is advantageously a thermal foam PVC. In this embodiment an additional layer of activatable adhesive may be used so that there is a layer of adhesive between each pair of adjacent layers of the underlying material.
If desired a die may be provided under the bottom layer for the purposes of welding a heel stiffener or a toe stiffener to the exposed face of the bottom layer at the same time as the assembly of the shoe upper.
The heel or toe stiffener may conveniently be made from a thermoplastics material.
Preferably the activatable adhesive can be activated by radiation such as high frequency radiation, infra red or ultraviolet radiation. The adhesive may be a heat activated adhesive such as a hot-melt adhesive.
Alternatively the adhesive may be activated by ultrasonic waves, or may be solvent activated.
It is desirable that the adhesive is cross-linked on or after activation.
In my prior UK Patent No. 1572789 the die form was provided with an angled surface on one side to produce the desired motif shape. In my UK Patent
Application No. 8206191,the preferred die form had a neutral severing edge in which the angles on each side of the edge are the same, or similar. In both prior specifications the roof of the die was located well above the severing edges so that the overlying layer was adhered to the substrate material only in the region in which the overlying material was severed.
In a preferred embodiment of the present invention the lamina of adhesive adjacent the overlying layer is acttivated over the whole surface area of the pattern to be applied. In this embodiment the distance between a part of the roof of the die which lies above those parts of the overlying layer which are intended to remain on the underlying material, and the tips of the severing edges, may be less than or equal to the thickness of the overlying layer. This causes the part of the overlying layer which forms the pattern to be flattened and compressed by the die thus resulting in the pattern being bonded to the underlying material over the whole of the surface adjacent to the underlying material.
In an alternative embodiment the lamina of adhesive adjacent the overlying layer is activated over a part of the surface area of the pattern to be applied.
The adhesive may subsequently be activated over the whole surface area of the pattern after it has been applied.
The die form may be provided with additional configurations to provide simulated stitching in the surface of the laminate. In one embodiment of the invention the simulated stitching can surround the
edges of each part of the pattern. Moreover both
positive and negative die forms may be used.
In addition the surface of the pattern may be
provided with a grained finish in order to simulate
leathers of various kinds, or quilting.
Afurther layer may be provided on top of the
overlying layer for the purposes of producing a
decorative effect on the part of the overlying layer
which forms the pattern. In this instance, the die can
be provided with an additional configuration for
stamping the decorative effect onto the overlying
layer. If the further layer is coloured differently from
the overlying layer then a "two-tone" effect can be
achieved. The further layer is advantageously a
printing foil. The additional configuration on the die should preferably have a flattened edge so that the
decorative effect is embossed, rather than cut, onto
the overlying layer, thereby preventing inadverten
tally causing damage to part of the pattern.
Reference is now made to the acompanying
drawings, in which:
Figure 1 is a perspective view with part cut away of
one form of die for applying a pattern according to
the preset invention;
Figure 2is a perspective view of a pattern pro
duced on an underlying material by the die shown in
Figure 1;
Figure 3 is a cross-section of the lines 3-3 of
Figures 2;
Figure 4 is a plan view of a shoe upper incorporat
ing a pattern, according to the invention; Figure is a cross section of a shoe upper prior to
assembly; and
Figure 6 is a cross section of a shoe upper after
assembly.
Figure 1 shows a die generally designated 1
having a base 2, and having an engraved form 3. The
die 1 is designed to produce an annular pattern as
shown in Figure 2. The extremities of the die 1
comprise severing edges 4, which also act as heating
zones.
In the method of the invention an underlying
material 5 (see Figure 2) is overlaid with an overlying
layer 7 of which only the part corresponding to the
pattern to be applied is shown. The die 1 is then
pressed into contact with the overlying layer 7 and
causes, due to heat provided by the heating zones of
the die, activation of a layer of hot melt adhesive 6
(see Figure 3) located between the overlying layer
and the underlying material 5. This causes the
adhesive 5 to melt and the overlying layer 7 is
thereby adhered to the underlying material 5. After
adhesion has been effected the die is removed and
the part of the overlying layer not corresponding to
the pattern can be removed leaving a pattern 7aon
the underlying material 5.
The distance between the tip of the severing edges
4 of the die 1 and the part of the roof of the die
indicated by reference numeral 8 is less than the
thickness of the overlying layer 7 so that the
overlying layer is flattened and compressed thus
bonding the whole of the lower surface of the
pattern 7a to the underlying material 3.
Another part of the roof of the die 1 indicated by
reference numeral 9 is arranged so that it does not come into contact with the overlying layer 7.
Figure 4 shows a shoe upper 10 which has been formed using the method of the invention. The shoe upper has patterned parts 11 (shaded) which are bonded to a top layer 12 of an underlying material 18.
In Figure 5 an overlying layer 11 and a layer of a hot melt adhesive 13a are arranged over the underlying material 18. The underlying material 18 comprises a top layer 12 of leather, an intermediate layer 14 of PVC foam and a bottom layer 15 of cotton or nylon. The foam layer 14, can serve the purpose of forming a padded collar. Layers of adhesive 13b and 13e a re provided between each layer of the underlying material. A toe stiffener 16 and an adhesive layer 13dare shown underneath the bottom layer 15.
A pattern from the overlying layer 11 can be applied to the upper surface of the top layer 12 by means of the die 1. Similarly die 17 can be used to apply the toe stiffener 16 to the lower surface of the bottom layer 15. The completed shoe upper 10 is shown fully assembled in Figure 6.
Although the present invention is described with particular reference to the applications of patterns to, and the assembly of, shoe uppers, it will be appreciated that the invention may be used in the manufacture of other multi-laminar articles, for example handbags.
