ABSTRACT:
An arrangement for timing the initiation of a spinning-in operation of an open-end textile machine is described. A sequencer is coupled to the take-up bobbin to provide an indication proportional to the increase in diameter of the yarn package during the take-up operation. The sequencer converts changes in such indication to a variable delay of signals to be applied to at least the take-up rollers and yarn-distributing rollers of the machine. The thus-delayed signals, whose delay is continually updated as the diameter of the yarn package increases, are applied to the appropriate rollers upon the detection of yarn breakage or other suitable initiation signal for the spinning-in mode.
