Luxembourg formed by: "dymo" public limited company for: "Sheet composed".

The present invention relates to a sheet composed of several layers, at least one layer of which is capable of changing appearance at a given location under the application of compression at this location.

Compound sheets of this kind are used in particular in the form of strips. Instruments comprising different! seals allow local compression to be applied to such tapes. The compression is exerted according to the particular form of the seal brought into contact with the strip. A local compression is thus applied in the form of a number, a letter or in general a sign. This sign can be a simple line, a punctuation mark, etc. . The local compressions modify the appearance of the above-mentioned layer and a band is thus obtained presenting these figures, letters or signs.

In known sheets of this kind, the layer liable to change in appearance under the application of local compression deforms and becomes white at the place where the compression was applied. In other words, the letters, numbers or signs that are created by local compressions appear in white and in relief. In other known sheets of the genus described, a coloring material, for example yellow in color, is included in the material of the layer capable of changing appearance under the application of local compression. Said layer also deforms at the place where the compression was applied but adopts the color of the coloring material there. If it is yellow, the letters, numbers or signs that are created by local compressions appear in yellow and in relief.

The invention aims to create a composite sheet whose aforementioned signs are not necessarily in relief and are not necessarily white or the color of the coloring matter included in the layer.

For this purpose the layer capable of changing appearance - 3 - is opaque and becomes less opaque under the application of compression.

In an advantageous embodiment of the invention the above opaque layer becomes transparent under the application of compression.

In a particular embodiment of the invention the aforementioned opaque layer is a layer of plastic material made opaque by orientation.

. In a preferred embodiment of the invention the above plastic material comprises an additive which is made opaque, but becomes less opaque under the application of compression.

Other details and particularities of the invention will emerge from the description of sheets composed according to the invention given below by way of nonlimiting example and with reference to the attached drawings.

Figures 1, 2 and 3 are sectional views of a sheet composed according to the invention and schematically represent the cachets by means of which the local compressions are applied.

In the three figures, the same reference numbers designate identical elements.

The sheets shown in the figures are composed of five layers indicated by the reference numbers 1 to 5.

Layer 2, which is specific for the composite sheet according to the invention, is opaque and becomes less opaque and preferably transparent at the location where local compression is applied. Opaque plastics which locally lose their opacity under the application of local compression are known in the trade. Such plastics are, for example, made opaque by hot or cold orientation. As plastics made opaque by hot or cold orientation, use may in particular be made of: - high density polyethylenes, - modified styrenes, for example butadiene, and - polyvinyl chlorides with additives, for example acrvl-nitrile butadiene-stvrene. or hase nolvmàres Λ

Layer 2 can also consist of a material which as such is not opaque. It then contains an additive which is made opaque, either by orientation, or by a chemical treatment carried out dry or wet. It is then the additive which becomes transparent or at least less opaque under the application of local compression.

As materials made opaque by a wet treatment, use may in particular be made of modified polyvinyl chloride manufactured according to a process producing an emulsion with additives, for example acryl-nitrile butadiene-styrene, or polymers based on acrylates .

The aforementioned chemical treatment can consist of an attack of the aforementioned materials by solvents.

The opaque layer 2 is covered with a transparent layer 1, called the upper layer.

The upper layer 1 can fulfill one or more of the functions described below.

Layer 1 can be a consistent layer, the main purpose of which is to form the formed sheet.

The upper layer 1 can be a sufficiently flexible layer to absorb the deformations under the application of compression. In other words, the layer 1 can be such that it allows the set of upper 6 and lower 7 seals to apply sufficient compression to the composite sheet and therefore to the opaque layer forming part of this sheet for this opaque layer 2 becomes transparent at the place of compression without the upper surface of the upper layer 1 having a significant deformation after the temporary compression has disappeared.

The top layer 1 can be colored.

The upper layer 1 can be simply protective of the opaque layer 2.

The upper layer 1 can also give a particular appearance to the assembly, for example by shaping or finishing. The whole can thus have the appearance of a textile coming only from a particular relief of the ennAvi ûnrû la annûrÎûnvû 1 h - 5 -

The underside of the layer 2 which is opposite the upper layer 1 and which is called the underside or base, may be colored. This coloration can be obtained by pressure or by application of a coloring matter.

This coloring material can constitute a separate layer 3, called the lower layer.

The face of the lower layer 3 which is opposite to the opaque layer 2 is in turn covered with an adhesive forming the layer 4. The οο11 ^ 4 is in turn covered with a coating layer 5. This coating layer 5 is located on the face of the adhesive 4 which is opposite to the layers 1, 2 and 3. This coating layer 5 can be flexible or rigid.

The materials of the different layers are chosen according to the characteristics desired for the assembly, in particular from the point of view of flexibility, resistance to temperature, resistance to ultraviolet rays and resistance to chemicals.

The set of five layers can be made in several different ways.

Different layers produced separately can be joined by dry or wet lamination. A layer can be formed by spinning while an already formed layer passes below or above the spinning head. Different layers can form together and be joined at the same time by a co-extrusion process. Two or more layers can also be joined by combined calendering and rolling.

The temporary and local compression of the assembly is carried out by the upper seal 6 which applies to the assembly on the side of the upper layer 1 and by the lower seal 7 which applies to the assembly on the side of the layer coating 5.

The term "stamp" should be understood in a broad sense and applies to any element which, in combination with a second element, is capable of applying local compression to the sheet. This local compression leaves an imprint in the sheet in the form of a local modification - the opacity of the layer 2. At least one of the two upper 6 and lower cachets? presents in relief or intaglio but preferably in relief a sign, for example a letter, a number, a line or a punctuation mark.

These seals belong to an instrument having for example the general shape of a clamp whose ends carrying the upper 6 and lower 7 seals can approach and move away from one another. Such instruments are known. At least one end of the instrument in the general form of a pliers then carries a disc which on the face directed towards the other end and near the edge of this face is provided with several seals, which one by one, depending on the user choice, can be placed in front of the composite sheet which rests on the other end of the instrument. This other end carries, for example, another disc which is moved with the aforementioned disc and which carries corresponding seals or is planar. If the two discs have stamps, the stamps of one of the discs are executed in relief while the cachets of the other are executed in hollow. In any case, the instrument applies the two seals 6 and 7 to the sheet so as to impose on it either compression only, or compression combined with deformation.

Figure 1 shows an upper seal 6 in relief and a lower seal 7 flat.

FIG. 2 represents a flat upper seal 6 and a lower seal 7 in relief.

FIG. 3 represents an upper stamp 6 in hollow and a lower stamp 7 in relief.

As follows from the description given above, each of the two seals can belong to a fixed member or to a mobile member belonging to the instrument which is to apply the chosen local compression.

The two seals are made of a material which is rigid enough not to undergo a significant deformation during the application of the compression to the composite sheet. Rigid plastics and metals are ideal for stamps.

The seals may belong to instruments known to apply compressions to bands on which signs must appear. They can also belong to known instruments used by engravers. These instruments can operate cold or be provided with means for heating at least one of the tablets or the composite sheet, when the latter is brought into contact with the tablets.

It is obviously by the fact that the opaque layer becomes transparent under the application of local compression that the signs appear and are visible through the upper layer 1. The apparent color of the signs will depend on the color of the opaque layer which becomes locally less opaque or transparent, but also of the colors of the upper layer 1 if this is colored and of the lower layer 3 if the latter is colored or of the color applied to the base of the layer 2 by printing or coloring any. Color combinations can give rise to particular effects.

It should also be noted that the composition of the lower layer 3 largely determines, for a constant pressure, the width of the signs which will be presented by the assembly after the application of the compression. Indeed, it is essentially the deformation of this layer which will determine over which width the compression will be felt for a determined relief stamp and for a given pressure.

The clarity of the signs will depend to a large extent on the choice of cachets. The most pronounced sharpness is obtained by a combination of an upper stamp 6 in hollow and a lower stamp 7 in relief, as shown in FIG. 3.

As already mentioned above, the sheet can be heated and the same is true for cachets. The opacity of layer 2 can be modified with less pressure if the sheet is heated.

It is also possible to heat one of the tablets and cool the other. This difference in temperature of the two cachets also makes it possible to obtain the same modification of the opacity of the layer 2 at a lower pressure.

Some examples of practical implementation are described above. In these examples, the thicknesses of the layers are indicated in mil, i.e. thousandths of an inch or about 0.0254 mm. PVC stands for polyvinyl chloride and P.E. stands for polyethylene.

It should be understood that the invention is in no way limited to the embodiments described above and that many modifications can be made to it, in particular as to the form, number, composition and arrangement of the elements involved in its realization without departing from the scope of this patent application.

Thus, for example, the layer which becomes less opaque or transparent under the application of compression can, in turn, be composed of several layers.

The sheet does not have to have a top layer. The opaque layer may be the top layer. The signs then appear in the color of the so-called lower layer on a colored background of the opaque layer. The signs can then appear in color on a white background.
