ABSTRACT:
A yarn false twisting apparatus is disclosed which comprises a pair of rotating circular discs having cooperating friction surfaces for engaging a running yarn at a twisting zone. The drive system for the discs includes a drive component which includes a drive whorl and a coaxial drive pulley, and which is adapted to engage two separate drive belts. The drive component includes a unitary tubular drive member, a central shaft extending through and fixed to the drive member, a sleeve mounted to the frame of the apparatus and extending between the shaft and drive member, and bearings positioned between the shaft and sleeve. Also, the drive component is mounted to the frame by an arrangement which permits adjustment of the rotational axis of the drive whorl about a second axis which perpendicularly intersects the rotational axis, so as to permit accurate alignment of the rotational axis of the whorl along a direction perpendicular to the running direction of the tangential drive belt. The discs are mounted to the frame by a bearing assembly which includes a tubular sleeve which is releasably mounted to the frame, a rotational shaft extending coaxially through the sleeve and mounting the disc at one end, and bearings positioned between the shaft and sleeve.
