A warp knitting machine for the purpose of carrying out the method comprises at least one thread system which consists of pattern threads laid in intermixed, varying patterns. These pattern threads have underlaps of n, n+1 and n-1 needle spaces and can produce a float and/or a twill. The number of pattern possibilities can be increased in this manner.

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.

Abstract: A warp knitting machine comprises a brake operative upon current interruption. The guide bars are displaced by an electrical setting motor as well as a control arrangement, which establishes the position of the guide bars in dependence upon the angular position of the main shaft. The control arrangement bases its control upon a predetermined displacement function relating the positions of the main shaft and guide bar. The setting motor and control arrangement are connected to a main power source via an intermediate circuit, which has at least one storage condenser. This machine allows for a rather rapid change of the lapping pattern and a continuance of controlled guide bar displacement right up to the standstill of the main shaft.

There is also provided a first storage section for storing data for various transition curves also relating to shogging patterns. A computer can generate a continuous displacement function based on the characteristic data and the transition curves. An output arrangement can reads out the values of the displacement function in dependence upon the rotation angle position of the main shaft 7 of the knitting machine. The values this read out are used as position target values for the guide bar. This enables flexible adaptation to produce very different patterns in high machine speed.

Abstract: A warp knitting machine comprises at least one guide bar and one main shaft. The angular position of the main shaft is determined by an absolute transmitter, while the position of the guide bar is determined by an absolute transmitter. Each transmitter can provide a different signal value for each angular position of the main shaft and for each guide bar position. A continuous displacement function is developed for the guide bar. This function relates each measured angular position of the main shaft with a position target value for the guide bar. A position control circuit controls a setting motor that displaces the guide bar. In this way, the danger of collision between elements of the guide bars and other working parts of the machine are practically totally avoided.

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.

Abstract: This invention relates to a stitch-bonding warp knitting machine and a process for operating it. The stitch-bonding warp knitting machine comprises a plurality of knitting needles that pierce a continuously conveyed band of material.
