Abstract: A warp knitted fabric has threads of a ground thread system forming a fabric ground. A pattern thread system also forms different patterned areas both in the weft direction as well as in the warp direction. In a basis area there is provided either cloth lapping (1-0/2-3-1 or 0-1/3-2-1). In the patterned area, a sequence is built by different lappings selected from a group consisting of pillar, tricot, cloth, satin and velvet stitches, in which the average length of the underlaps in predetermined pattern repeats is substantially similar to the underlap length of the cloth lapping. This gives rise to numerous new patterning possibilities, in particular for a jersey fabric. In addition to a described process, a warp knitting machine is provided for making such warp knitted goods.

Abstract: A control arrangement for the shifting movement of at least one guide bar (4) contains a pick-off gear (10) against which the guide bar is pretensioned. The pick-off gear (10) has a plurality of thrust elements (8, 8.sub.1, 8.sub.2, 8.sub.3) connected one behind the other, between which displacement elements (12.sub.1, 12.sub.2, 12.sub.3, 12.sub.4) are arranged, the thrust elements (8, 8.sub.1, 8.sub.2, 8.sub.3) being supported on the radial cams (34) of the displacement elements (12.sub.1, 12.sub.2, 12.sub.3, 12.sub.4). The displacement elements (12.sub.1, 12.sub.2, 12.sub.3, 12.sub.4) are connected via coupling members (16) to a pattern controlled adjusting device (18) and can be adjusted between a basic position and a switched position.

Abstract: A control arrangement for displacing the guide bar in a warp knitting machines comprises an input arrangement for the setting certain characteristic data defining the desired shogging pattern. 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 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.

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: In a warp knitting machine at least one swingable guide bar is driven in a shogging direction. This displacement is achieved through a drive member via a hinged push rod in dependence upon a path time function. This path time function is formed by overlapping a ground function with a compensation function. The ground function is the targeted displacement movement of the guide bar for proper lapping. The compensation function compensates for an axial mislap and possible collision during the swing-through of the guide bar. The compensation occurs at least during that segment corresponding to the passage of the guides through the needle gaps. Preferably however, compensation occurs over the entire ground function. This compensation substantially reduces the danger of collision between the guides and the needles.
