Abstract

A belting with a single-layer central portion and two tubular edge portions is made on a needle ribbon weaving machine with one of the tubular edge portions woven as a single layer and then closed to form the tubular edge portion by exerting a pull on the weft thread; a knitting course maintains the tubular edge portion closed along its joint by means of a tuck thread and/or an interlocking thread which is buried in the fabric by feeding a greater length of tuck thread in the knitting course than usual or by laying in the interlocking thread into the head of the knitting needle from vertically above the knitting needle.
