ABSTRACT:
Two warp sheds are formed from warp threads at least some of which are meltable. The warp threads are preheated to make them deformable and weft threads are inserted into the respective sheds and beaten-up in order to form two superimposed fabrics which are connected by the meltable warp threads. During the beating-up the weft threads and the meltable warp threads are simultaneously heated so as to make them adhere to one another. The resulting fabrics are cooled to reverse the deformability of the meltable warp threads, and thereupon the latter are severed intermediate the fabrics by application of heat while the severed ends of the meltable warp threads are simultaneously deformed.
