<p>A composite piece 9 comprises at least two layers 3,5 of flexible materials which may be identical or different. Adjacent layers 3,5 are bonded by multiplicities of interposed thermoplastic beads 7 which lie equally spaced along parallel lines and adhere to both adjacent layers. The piece 9 may be made by passing layers 3,5 and an interposed thermoplastic (preferably high-density polyethylene) lattice having the form of beads linked by thin threads through a heated calendar 1,2, whereby the threads are melted away and the beads 7 heat-welded to the layers 3,5. One or both external faces may be dyed or printed simultaneously with the head-welding step by including transfer paper(s) 11,12 in the "sandwich" passed through the calendar. The composite pieces 9 may be applicable to e.g., furnishings and clothing, and especially to reversible garments.</p> |
