Abstract: In an electromagnetically operated, jacquard control arrangement, each controllable element is provided with an electromagnet cooperating with an anchor. An actuating current switch can energize the electromagnet arrangement. A swingably mounted control element provides a movable contact point on a lever arm for moving controllable elements. A swingable synchronization arrangement is driven back and forth by a continually rotating main shaft which can also turn the control element in one direction over a predetermined working angle. A return spring, in dependence upon the activation condition of the electromagnet, can swing back the control element. At the beginning of each working cycle the anchor is positioned proximate the poles of the electromagnet. The anchor is attached to the control element. The anchor of the control element may be carried by the synchronization arrangement.

Abstract: In a control arrangement for the motor of a winding arrangement, such as a partial warp beam in a warp knitting machine, there is provided a controller. The controller controls the rate of rotation of the motors of the turning arrangements that influence thread consumption and ware takeoff, in dependence on a main shaft signal, a feedback signal and an input size signal. The control arrangement is equipped for the storage of a program containing many input sizes which are addressable sequentially for the control arrangement, in dependence upon the main shaft signal. In particular, a data memory may be provided with a plurality of addresses for the production of differentiable input sizes. An address caller is controlled by the main shaft signal and calls out sequentially the different input sizes for the control arrangement. As a controller, a digital computer is foreseen.

Abstract: A summing arrangement controls the shogging movement of a guide bar of a warp knitting machine. The arrangement has a plurality of ordered elements each having at least one curved face. The ordered elements are mounted on the machine to allow a variation in the spacing between each. Also included is a plurality of adjustable roller devices, one between each adjacent pair of elements. Each of these roller devices can roll upon and push at least one of the elements at its curved face.
