Abstract

Abstract A wall covering has a textile element secured to a backing by a thermo-fusible material. The textile element is formed of compacted zig-zags of the warp formed by a crocheting machine and held on the backing by chain stitching parallel to the direction of movement in the machine. The chain stitching along the selvage edges of the element precut the backing for removal of excess backing by tearing. The covering is coupled by a final step of fusing the thermo-fusible material.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 213 words
A wall covering composed of an element of a textile nature associated with a support of dimensionally indeformable material on which support the textile element is fixed by the fusion of a film of thermoplastic material interposed between the textile element and the support, the textile element being formed by crocheting with deposit of at least one warp band of threads or meshes in a zigzag having the portion of the warp substantially perpendicular to the direction of advance of the work prefixed in this position by chain stitching parallel to the direction of advance of the work, the textile element being of the exact width of the final covering and stabilized in width and straightness by the support of width greater than that of the textile element, the textile element being prefixed to the support and film by the chain stitching that positions the portions of the warp, chain stitching along each edge of the warp to prevent the marginal portions of the warp from displacing before being fixed by fusion of the film and providing 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 the fused film positively fixing the textile element on the support.
