Abstract: A multitwist spindle for processing of fibers and yarn by twisting and combining materials from at least two countershafts with equal or different heights of twist while simultaneously forming a left and right twist or a single direction combined twist. The spindle has at least one rotating shaft with a yarn carrier fixed to it and at least two rotating countershafts on which the yarn is mounted.

Abstract: A winding machine with a multitwist spindle for textile working of fibres and yarn with a synchronized movement of the multitwist spindle and the winding-on mechanism, both of which are mutually independently supported by a supporting frame.

Abstract: Filaments or yarn are twisted by means of an arrangement provided with three at least partly hollow shafts rotating at equal or different rotating speeds and in the same or different sense, while the fibrous material is guided so as to pass alternately through the hollow shafts when taken off from a supply package and to carriers fixed to these shafts, to be thereby twisted and taken off by a take-up device.

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.
