ABSTRACT:
At least one pattern thread (8) is bound into the fabric ground in a process for producing a patterned knitted fabric (12). The process uses a warp knitting machine having one needle bar (1), at least one fabric ground laying bar (2,3a), at least one pattern laying bar (9) carrying guides (7) for pattern threads and a knock-over arrangement (9) over which the fabric (12) can be pulled. The pattern thread (8) is grasped, by a grasping device (16), and held between the pattern thread guide and the knock-over arrangement (9). The grasped pattern thread is then severed proximal to the knock-over arrangement, by a cutting device (13). The severed pattern thread is held out of the knitting process for a predetermined time, before being bound again into the fabric ground, no earlier than after a new stitch formation. The excess pattern thread is again severed near the knock-over arrangement (9) and the freed thread cuttings removed. Also disclosed is a warp knitting machine for the formation of such a patterned fabric. In effect, a single pattern thread (8) can form pattern segments which are separate from each other. This is achieved in a cost effective and space saving manner, as well as with reduced thread loss.
