  • Patent number: 5297402
    Abstract: A process for the production of warp knitted fabric uses a ground guide bar (L1) and at least two guide bars (L2 and L3) with partial threading. Threads (14) of a first additional thread system are worked with a main lap, which comprises a two row repeat. Threads (15) of a second additional thread system alternate between this main lapping and a pattern lap. Thread consumption in in the pattern lap are kept the same as in the main lap by using displacements that are larger and smaller than that in the main lap. A warp knitting machine (1) for providing such a process comprises appropriate control arrangements ( 6, 7, 8) for the displacement of the ground guide bar (L1) and the additional guide bars (L 2, L3). Furthermore, a novel warp knitted fabric is produced thereby. It is thus possible, by simple means, to produce a warp knitted fabric which is differently structured both in the warp direction, as well as in the weft direction.
