Abstract
In a ring spinning or other textile machine with a multiplicity of thread-winding stations each including one or more variable-speed motors, a central controller supplies periodic or continuous timing signals to respective speed setters of all stations for a predetermined progressive speed change of the associated variable-speed motors. In a specific embodiment, the timing signals are recurrent pulses for the advance of identical programs of the local speed setters whereby the several stations will follow the same routine but with possible relative staggering in time, taking individual delays due to thread breaks or the like into account.
