Abstract

A starting device for a winding reel, such as a warping mill for textile threads, uses a thyristor in the armature circuit of the d.c. drive motor. The thyristor is controlled by a pulse generator, in a cascade with a speed comparator and an armature current comparator. The former compares a voltage, supplied by a tachometer, with a voltage proportional to the desired speed. The latter compares the actual current with the desired current setting. Both comparators are preceded by a change-over switch. This requires few and uncomplicated elements to apply first a gentle tension and to observe the reel at a crawling speed before changing over to nominal full speed.
