Title: Method of and apparatus for twisting yarn or thread

Abstract: A system for the spinning or twisting of thread or yarn in which a thread is supplied by a strand-supply spool and is collected on a strand-takeup spool so that the strand spans the distance between the spools over a predetermined length, the twist-generating spool being driven for a predetermined number of turns to bring the number of twists over the length to the normal twisting level before the two spools are operatively connected together for joint operation at the normal rate. The delay between operation of the nontwist-generating spool and the twist-generating spool is created by a counter responsive to the number of twists produced in the length during the interval.
