Title: Thread storage feeder

Filed: 1972-05-25
Abstract: 1390053 Yarn storage feeders; thread unwinding apparatus K I J ROSEN 25 May 1972 [25 May 1971] 24815/72 Headings D1C and D1J In a thread storage feeder yarn F from a bobbin 2 is wound tangentially on a storage drum 7 and continuously taken off axially, and the electric motor driving the drum is switched off and on rapidly by a device 9 which senses when the yarn on the drum varies from a mean value, so that the supply of yarn wound on the drum is kept nearly constant. The sensing ring 9 is normally tilted, but is forced to pivot to the dotted position when the yarn supply 17 increases, thus causing a pin 10 to press a plunger 15 and open the electrical contacts 13. This switches off the electric motor, which comes on again as the yarn supply decreases and the ring 9 tilts again. The switch 11 is placed in the line to the control electrode of a thyristor which switches the current to the electric motor. The drum is thus kept in motion.
