Process for manufacture of wall coverings and wall coverings thus obtained

Claim 1

Process of manufacture of a complex providing a wall covering and composed of an element of textile nature associated with a support of dimensionally indeformable material on which support the textile element is fixed by fusion of a film of thermoplastic material interposed between the textile element and the support, the steps of forming the textile element on a crocheting machine for the deposit of at least one warp band of threads or meshes in zigzags the peaks of which are substantially perpendicular to the direction of advance of the work, prefixing the warp in position by chain stitching parallel to the direction of advance of the work, forming the textile element in at least one layer exactly to the width of the final covering, stabilizing the textile element in width and straightness by supplying the machine with a support and fusible film of greater width than that of the said element, prefixing the warp to the support and film by the chain stitching which also positions the sections of the warp, locating certain of said chain stitching on the warp along each edge of the warp to prevent the marginal portions of the warp from moving before fixing by fusion of the film and in such a way that each edge stitching of the warp provides a line of precutting of the support and of its film to facilitate the ultimate tearing away of the excessive width of the support, and then heating the warp fiber and support to fuse the film and positively fix the textile element on the support.
