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. The switching arrangement is provided with a timing device which maintains the activation of the electromagnet commencing at the beginning of a work cycle over the major portion of the work cycle.
