DELIVERY DEVICE FOR THREADS ON WEAVING MACHINES, KNITTING MACHINES, OR THE LIKE

摘要

A delivering device for threads on weaving machines, knitting machines, or the like, which comprises a motor and a drum which is rotated by the motor and adapted to store intermediately a predetermined thread supply prior to each thread removal. A thread supply surveillance device is arranged for stopping the motor upon reaching a nominal-thread supply. The motor comprises an asynchronous two-phase motor. A current valve circuit is provided for feeding current to the motor. The surveillance device emits a motor stopping-command signal in both phases in the stopping position, and the current valve circuit is transferred by the command signal for either positive or negative half-waves.
