    • The tensioner has convex-faced washers (10) pressed together, passing the thread, with a central opening (44) through which bearing pins (20) pass and upon which the washers rotate. A U-shaped holder (19) has limbs (21) either side of the tensioner, which carry the bearing sections. An Independent claim is included for the yarn supply unit, including the tension controller and supply drum. Preferred features: The holder is a bent piece of wire including formed bearing eyes. It has two parallel sections with adjustable projection from its mounting (14). One end of the holder is oscillated under spring loading, coupled into the holder. One of the limbs is bent or offset. The bearing is detachable from the holder and adjustable on it. The bearing section is approximately U-shaped. Its frame is clipped onto the holder. It can be held fixed in a working position, or folded-back. A region on the frame (40) supports the tensioner. The frame is detachably clamped to the holder and has divided construction. Further structural details include the plastic bearing section, earthing and thread guidance.

    • PCT No. PCT/DE96/01751 Sec. 371 Date Apr. 2, 1998 Sec. 102(e) Date Apr. 2, 1998 PCT Filed Sep. 17, 1996 PCT Pub. No. WO97/13906 PCT Pub. Date Apr. 17, 1997For supplying yarns, a yarn supply apparatus is contemplated that is designed particularly for knitting machines whose yarn demand fluctuates greatly over time. The yarn supply apparatus has a rotor-driven yarn wheel, which in the ideal case furnishes yarn directly to the knitting machine or its yarn guides without the interposition of yarn storage devices. The yarn tension is monitored by means of a yarn tension sensor, which provides measured value detection for a closed-loop controller that controls the supply by the yarn wheel. The controller is also embodied such that it can process signals that contain information about the future yarn demand. Thus in the event of imminent drastic changes in demand, of the kind that in flatbed knitting machines periodically occur at the edges of the knitted goods (turning points of the yarn guide), the controller can react by presupplying yarn or by ceasing to supply yarn. Yarn tension spikes and overly steep yarn tension drops can thus be compensated for. The controller may be designed such that it functions as a closed-loop status controller and intermittently as an open-loop controller. Other provisions, such as disturbance variable compensation, parameter adaptation, or the like, are possible.
