Abstract

Process for the manufacture of an expanded structure the main part of which is made of leather and the straps of which are situated in the same plane and together form perfectly uniform meshes. This process is characterised in that the skin or sheet of leather is impregnated with a resin or an adhesive in sufficient quantity for the excess part, which is not absorbed by the pores of the skin, to form under the latter a thin film or sheet of resin or of adhesive forming an underlayer, and the resin or the adhesive is chosen with a nonelastic character and without memory so that the underlayer thus formed remains open after expanding and resists the retraction of the skin or of the sheet of leather with which it is intimately bound.

Description

Le brevet principal a pour objet un procédé de fabrication d'une structure déployée dont la partie principale est en cuir et dont les lumières sont situées dans un même plan et forment entre elles des mailles parfaitement régulières, caractérisé en ce qu'on double. avant déployage, les peaux ou feuilles de cuir avec une feuille mince constituant une sous-couche en matériau très peu élastique et suffissmment résistant pour supporter l'opération de déployage, autrement-dit avec une feuille mince eÀ matériau déployable sans retrait, ainsi que la structure obtenue suivant ce procédé. The main patent relates to a process for manufacturing a deployed structure, the main part of which is made of leather and the lights of which are located in the same plane and form perfectly regular meshes between them, characterized in that one doubles. before unfolding, the skins or sheets of leather with a thin sheet constituting an underlayer of very inelastic material and sufficiently resistant to withstand the unfolding operation, in other words with a thin sheet and deployable material without shrinkage, as well as the structure obtained according to this process.

La présente addition A pour but de simplifier les opérations nécessaires pour la fabricstion de la structure. The purpose of this addition is to simplify the operations necessary for fabricating the structure.

Suivant la présente addition on imprègne la peau ou feuille de cuir avec une résine ou une colle en quantité suffisante pour que la partie en excès, qui n'est pas absorbée par les pores de la peau, vienne former sous celle-ci un film ou une feuille mince de résine ou de colle constituant une sous-couche. et on choisit la résine ou la colle avec un caractère non élastique et sans mémoire de telle façon que la sous-couche ainsi constituée reste ouverte après déployage et s'oppose au retrait de la peau ou de la feuille de cuir avec laquelle elle est intimement liée. According to the present addition, the skin or sheet of leather is impregnated with a resin or a glue in sufficient quantity so that the excess part, which is not absorbed by the pores of the skin, comes to form under it a film or a thin sheet of resin or glue constituting an undercoat. and one chooses the resin or the glue with a non-elastic character and without memory so that the undercoat thus constituted remains open after deployment and opposes the removal of the skin or the sheet of leather with which it is intimately linked.

On peut citer, à titre d'exemple non limitatifs, comme résine ou colle pouvant être- utilisée à cet effet, les résines à base d'acrylique et les colles à base de polyuréthane. Mention may be made, by way of nonlimiting example, as resin or glue that can be used for this purpose, acrylic-based resins and polyurethane-based glues.

On paut également prévoir une imprégnation avec une colle réactivable à chaud, c'est-à-dire qui redevient fluide à une certaine température en conservant toutes ses propriétés. I1 existe plusieurs types de colle possédant cette propriété et on peut citer les colles dites "Hot Melt" et celles réactivables à base de polyuréthane de type mono ou bicomposant. Ce type dt imprégnation permet d'assurer, par simple réchauffage, l'adhérence de la structure déployée sur un quelconque support pour constituer un complexe, la colle devant être choisie pour que sa température de réactivation se situe au-dessus des températures limites envisagées pour l'utilisation du complexe. It is also possible to provide an impregnation with a hot-reactivable adhesive, that is to say which becomes fluid again at a certain temperature while retaining all of its properties. There are several types of glue having this property and mention may be made of so-called "Hot Melt" glues and those reactivable based on polyurethane of the mono or two-component type. This type of impregnation ensures, by simple reheating, the adhesion of the structure deployed on any support to form a complex, the adhesive having to be chosen so that its reactivation temperature is above the limit temperatures envisaged for use of the complex.

Après l'opération de déployage on peut avantageusement procéder à une opération de pressage pour aplanir les lanières.  After the deployment operation, it is advantageously possible to carry out a pressing operation to flatten the strips.

REVENDICATIONS 1.- Procédé de fabrication d'une structure deplo- yée dont la partie principale est en cuir et dont les lanières sont situées dans un même plan et forment entre elles des mailles parfaitement régulières suivant la revendication 1 du brevet principal, caractérisé en ce qu'on imprègne la peau ou feuille de cuir avec une résine ou une colle en quantité suffisante pour que la partie en excès, qui n'est pas absorbée par les pores de la peau, vienne former sous celle-ci un film ou une feuille mince de résine ou de colle constituant une sous-couche, et on choisit la résine ou la colle avec un caractère non élastique et sans mémoire de telle façon que la sous-couche ainsi constituée reste ouverte après déployaqe et s'oppose au retrait de la peau ou de la feuille de cuir avec laquelle elle est intimement liée. 1.- Method of manufacturing a deployed structure, the main part of which is made of leather and the straps of which are located in the same plane and form between them perfectly regular meshes according to claim 1 of the main patent, characterized in that '' the skin or sheet of leather is impregnated with a resin or a glue in sufficient quantity so that the excess part, which is not absorbed by the pores of the skin, comes to form under it a film or a thin sheet of resin or glue constituting an undercoat, and the resin or glue is chosen with a non-elastic character and without memory so that the undercoat thus formed remains open after deployment and prevents the skin from being removed or the sheet of leather with which it is intimately linked. 2.- Procédé suivant la revendication 1 caractérisé en ce que l'on utilise, pour imprégner la peau ou la feuille de cuir r une colle réactivable à chaud de manière à pouvoir réaliser par la suite l'adhérence de la structure déployée sur un quelconque support. 2.- Method according to claim 1 characterized in that one uses, to impregnate the skin or the leather sheet r hot-reactivable adhesive so as to be able to subsequently achieve the adhesion of the deployed structure on any support. 3.- Procédé suivant l'une quelconque des revendications précédentes caractérisé en ce qu'après l'opération de déployage. on procède à une opération de pressage pour aplanir les lanières.  3.- Method according to any one of the preceding claims, characterized in that after the deployment operation. a pressing operation is carried out to flatten the strips.
