Abstract (en)
[origin: EP0945534A2] The tensioner (15) extends and tensions the thread to a set degree. The thread is wound a few times round the motor-driven feed wheel (16). At the feed wheel, leading tension does not influence trailing tension. The motor (17) feeds thread solely in accordance with thread demand. Its control is independent of the tensioner itself, and of tension arising in the section after the feed wheel. An Independent claim is included for the corresponding method of feed control. Preferred features: In one variant, the tensioner is a thread brake operating independently of thread speed. The sensor (24) measures tension between tensioner and feed wheel, adjusting braking accordingly. The friction brake used, has fixed or adjustable loading. An electrically controlled actuator operates it. A belt brake is employed, the controller (18) adjusting wrapping angle through an electrical actuator. Further variants, based on the foregoing principles, are described. The method provides that, following withdrawal from the supply spool, extension is such that no increase in tension causes further reversible extension.
