PROCESS AND THREAD INSERTER FOR THE MANUFACTURE OF A BELTING WITH TUBULAR EDGE PORTIONS Abstract Belting for use preferably for safety belts in motor vehicles has a single layer woven central portion and two tubular edge portions and is made on a needle belt weaving loom provided with a knitting needle. One tubular edge portion is closed by a row of stitching that does not lie at the outer edge of the edge portion but disappears into the fabric at the edge of the central portion. By means of the invention the rate of production is increased by using two weft thread insertion needles that simultan- eously insert two weft threads at each pick. A common shed for these needles is formed by the two outer edge warp threads. For weaving the edge parts between the central portion and the two outer edge warp threads, an upper shed and a lower shed are formed. Of these, one shed accepts the first weft thread insertion needle which forms the edge fabric and the other the second weft thread insertion needle. A loop is drawn by the knitting needle outside the edge part through a loop of at least one of the weft threads to form a stitch.
