Abstract
The invention relates to a device for controlling the take-up speed of a winding frame for textile yarns, which winding frame has peripheral drive by means of a pilot roller and axial drive by means of a gas turbine integral with the spindle which carries the winding. The device acts when the winding is out of contact with the pilot roller. The control device includes: a calculating unit which, using pulses originating from the pilot roller, emits pulses at a required frequency of the spindle, and a frequency comparator which compares the frequency of pulses originating from the rotating spindle with the required frequency, and which, from the comparison, controls a device for regulating the fluid supply of the turbine. Several winding frames can be simultaneously controlled. The device can be used to provide the spindle with an overspeed at the start of winding, in order to avoid drops in tension.
