ABSTRACT:
When spinning is to be started or restarted after interruption, an operator places a combination spool support and electronic pack on tracks at the spinning station, locates the pack in spool-supporting position, electrically connects the pack with a spinning station connection, draws a predetermined length of thread from the takeup spool, inserts it into the drawoff tube, and actuates a switch on the pack. The pack contains an electronic timing circuit, which sequentially effects starting of the fiber supply to the spinning chamber, and, after a predetermined time delay, effects reengagement of the thread takeup spool with its drive roller.
