ABSTRACT:
Multi-twist spindle having a supporting element for a feeding bobbin carrying a coil of an elongated strand, a brake through which the strand from the bobbin passes to an inner main carrier, and an inner auxiliary carrier driven by an inner main pulley, and an inner auxiliary pulley, the two said pulleys being speed and phase synchronized by a transmission including an elongated shaft spanning the distance between the two pulleys. After passing through the inner auxiliary carrier the strand goes through an outer main carrier and an outer auxiliary carrier rotating in a direction opposite to the inner carriers and carried by aligned outer main shafts which are speed and phase synchronized. Each set of main and auxiliary carriers constitutes a carrier couple which carries out two twists of the strand per one revolution.
