Abstract

Small offcuts of leather, resulting from cutting large leather sheets in the mfr. of convential leather prods., are collected for sorting. Offcuts of similar thickness and with similar characteristics are joined together by adhesive between overlapped edges of offcuts. The adhered overlaps are then positively fixed together by sewing. The assembled patchwork of offcuts is then subjected to normal leather finishing operations. The patchwork sheet is suitable for making most leather goods which are usually made from whole sheets, e.g clothing such as waistcoats, handbags, suitcases and other luggage. Offcuts of leather which were previously scrapped can now be economically recovered as patchwork leather sheet. Careful selection and assembly of the offcuts can produce an esthetically pleasing sheet from which attractive, inexpensive prods will result.

Description

La présente invention concerne un procédé de fabrication d'articles en cuir ainsi que des articles obtenus par ce procédé. The present invention relates to a method for manufacturing leather articles as well as articles obtained by this method.

Les articles fabriqués actuellement en cuir sont constitués de morceaux de cuir de grandes surfaces découpés aux dimensions appropriées et assemblées entre eux par couture. Le découpage de ces morceaux de cuir dans les peaux initiales se traduit par la production de chutes de petites dimensions qui sont généralement mises au rebut, ce qui se traduit par une perte d'un matériau présentant une valeur économique certaine. The articles currently manufactured in leather are made of pieces of leather of large areas cut to the appropriate dimensions and assembled together by sewing. The cutting of these pieces of leather in the initial skins results in the production of small scraps which are generally discarded, which results in a loss of a material having a certain economic value.

La présente invention a pour but de remédier à cet inconvénient en procurant un procédé permettant de récupérer ces chutes pour fabriquer des articles présentant un aspect esthétique certain. The object of the present invention is to remedy this drawback by providing a method making it possible to recover these falls in order to manufacture articles having a certain aesthetic appearance.

A cet effet ce procédé de fabrication d'articles en cuir est caractérisé en ce qu'on récupère des chutes de petites dimensions résultant de la coupe de pièces de cuir de grandes surfaces, on rassemble deçchutes-sen- siblement homogènes quant à leur épaisseur et à leur nature, on les fait se chevaucher les unes les autres par leurs parties marginales, on les assemble entre elles tout d'abord par collage des parties en contact les unes avec les autres, puis par couture le long des bords des diverses chutes, et on procède aux opérations de finissage habituellement pratiquées sur les cuirs et peaux de dimensions naturelles (pigmentation, transfert, satinage, grainage). To this end, this method of manufacturing leather articles is characterized in that small scraps are recovered resulting from the cutting of pieces of leather from large areas, collapsed pieces are gathered-substantially homogeneous as regards their thickness and by their nature, they are made to overlap each other by their marginal parts, they are assembled together first by gluing the parts in contact with each other, then by sewing along the edges of the various falls, and we proceed to the finishing operations usually practiced on hides and skins of natural dimensions (pigmentation, transfer, satin finish, graining).

Le procédé suivant l'invention permet de fabriquer, à partir des chutes ainsi récupérées, des articles divers tels que sacs, valises, vêtements, etc, qui présentent un aspect extérieur particulièrement original, cet aspect pouvant être modifié à volonté, lors de la fabrication de l'article, en déterminant d'une manière judicieuse la disposition relative des diverses chutes. The method according to the invention makes it possible to manufacture, from the scraps thus recovered, various articles such as bags, suitcases, clothing, etc., which have a particularly original external appearance, this appearance being able to be modified at will, during manufacture. of the article, by judiciously determining the relative disposition of the various falls.

L'invention a également pour-objet un article à base de chutes de cuir se chevauchant les unes les autres, collées et cousues ensemble, obtenu par le procédé suivant l'-nvention. The subject of the invention is also an article based on scraps of leather overlapping each other, glued and sewn together, obtained by the process according to the invention.

On décrira ci-après, à titre d'exemple non limitatif, une forme d'exécution de la présente invention en référence au dessin annexé sur lequel
La figure 1 est une vue en plan d-'une partie d'un article fabriqué à partir de chutes de cuir.An embodiment of the present invention will be described below, by way of non-limiting example, with reference to the attached drawing in which
Figure 1 is a plan view of part of an article made from scraps of leather.

La figure 2 est une vue en coupe partielle prise suivant la ligne II-II de la figure 1. Figure 2 is a partial sectional view taken along line II-II of Figure 1.

L'article fabriqué par le procédé suivant l'invention et qui est représenté sur les figures 1 et 2, est constitué de chutes provenant de la coupe de pièces de cuir de grandes dimensions et qui sont utilisées par ailleurs pour la réalisation classique d'articles vestimentaires ou utilitaires. Le procédé suivant l'invention vise à récupérer ces chutes qui sont choisies de.maniè- re à présenter-une certaine homogénéité quant à leur épaisseur et à leur nature. Par exemple sur la figure 1 sont représentées cinq chutes 1, 2, 3, 4, 5 dont les formes sont soit celles qui résultent de la coupe elle-même, soit des formes légèrement adaptées, par exemple pour donner des morceaux de petites dimensions de forme sensiblement allongée.Ces chutes 1-5 sont disposées suivant un agencement donnant éventuellement un effet esthétique recherché, de manière à se chevaucher mutuellement. Commeon peut le voir sur la figure 1, la chute 2 chevauche la chute 1, la chute 3 chevauche les deux chutes 1 et 2, la chute 4 chevauche les chutes 3 et 1 et la chute 5 chevauche les chutes 1 et 4. Le chevauchement des chutes entre elles s'effectue le long des parties marginales de celles-ci et, une fois choisie la disposition mutuelle des chutes, on procède à un assemblage de ces chutes par collage des parties en contact. Ce collage conduit à l'obtention d'une nappe formée en quelque sorte par une "mosaïque" de chutes qui se chevauchent en partie mutuellement. Une fois les chutes individuelles collées les Unes aux autres, on procède à leur assemblage définitif en effectuant des coutures 6 à travers les chutes superposées et le long des bords de ces chutes, comme illustré sur les figures 1 et 2. The article produced by the process according to the invention and which is represented in FIGS. 1 and 2, consists of scraps originating from the cutting of large pieces of leather and which are also used for the conventional production of articles clothing or utility. The method according to the invention aims to recover these falls which are chosen so as to present a certain homogeneity as regards their thickness and their nature. For example in FIG. 1, five scraps 1, 2, 3, 4, 5 are represented, the shapes of which are either those which result from the cutting itself, or slightly adapted shapes, for example to give pieces of small dimensions of substantially elongated shape. These falls 1-5 are arranged in an arrangement possibly giving a desired aesthetic effect, so as to overlap each other. As can be seen in Figure 1, the fall 2 overlaps the fall 1, the fall 3 overlaps the two falls 1 and 2, the fall 4 overlaps the falls 3 and 1 and the fall 5 overlaps the falls 1 and 4. The overlap falls between them is carried out along the marginal parts thereof and, once the mutual arrangement of the falls has been chosen, these falls are assembled by gluing the parts in contact. This bonding leads to the production of a sheet formed in a way by a "mosaic" of falls which partially overlap each other. Once the individual falls have been glued together, one proceeds to their final assembly by making seams 6 through the superimposed falls and along the edges of these falls, as illustrated in FIGS. 1 and 2.

On obtient alors une nappe composite très solide que l'on soumet à toute opération de finissage habituellement pratiquée sur les cuirs et peaux de dimensions naturelles (pigmentation, transfert, satinage, grainage). On fabrique ainsi un article très résistant et présentant un caractère esthétique pouvant être utilisé pour la réalisation de vêtements, tels que vestes, blousons, etc, ou autres articles utilitaires tels que sacs, valises, etc. A very solid composite sheet is then obtained which is subjected to any finishing operation usually carried out on hides and skins of natural dimensions (pigmentation, transfer, satin finishing, graining). This produces an article very resistant and having an aesthetic character that can be used for the production of clothing, such as jackets, jackets, etc., or other utility items such as bags, suitcases, etc.
