2081373 9114814 PCTABS00007 Process for weaving a ribbon on a needle ribbon-weaving machine with two weft needles (26, 28) which work in opposite directions. In one embodiment of a process for manufacturing a ribbon, a middle part (1) is woven from a weft multithread and a weft monothread (12, 10), while two edge parts (5, 6) are woven from a single weft multithread (12). The ribbon has high transverse strength but the edges are soft. A main shed (39) for both weft needles (26, 28) is formed from the warp threads (3) of the middle part (1). A partial traverse shed (38), through which only the weft needle (28) for the multithread (12) is inserted, is formed for each of the two edge parts (5, 6). The heads (14) of weft loops which are interlaced with the edge part weft threads (8) are secured by a row of stitches (18) located at the outer side of the edge part. The heads (24) of weft loops which are interlaced only with the middle part weft threads (3) are secured by a row of stitches (20) located at the outer edge of the middle part (1) and on the inner edge of the adjacent edge part (5). In a second embodiment for weaving a ribbon with two weft needles working in opposite directions, the ribbon is woven by inserting both weft needles into a common shed. The heads (60, 66) of the weft loops inserted in opposite directions are secured by two rows of stitches (62, 68) each formed from an auxiliary thread and located at the two outer edges of the ribbon. This ribbon has no edge parts but is absolutely symmetrical, and it has outer edges which are protected by the two rows of stitches (62, 68) and are soft.
