Abstract
An apparatus is disclosed for the variable speed control of cams in a textile machine to provide for high speed winding of thread on spools which are controlled by the cams. A motor drives each cam. The speed of each motor is varied according to a predetermined cycle to produce a staggering of the thread on the spools from one layer to the other and to avoid the formation of bunches on the formed winding. The motors have a common induction supply which establishes the motors average speed and which operates to exchange the braking energy of the motors The driving energy applied to the motors is modulated in opposite phase in order to achieve variations around the average speed of the motors by inductively varying the flux of the motor windings.
