Abstract: The invention relates to a device for compacting a sliver (V) on a spinning machine, the sliver being delivered by a pair of delivery rollers (7, 8) of a drafting system unit (2) to a suctioned guide surface of a suction zone (Z) of a subsequent driven, revolving compaction element (17) that is acted on by suction air. At least one rotatably supported nip roller (33) is associated with the compaction element downstream from the suction zone (Z) to form a nip line (P). To retrofit existing spinning machines with a compaction device, heretofore additional complex drive means have been installed, sometimes requiring a very high expenditure of time for installing such devices.

Abstract: The invention relates to a spinning machine, the drafting arrangement of which comprises a drafting arrangement unit (35, 65, 95) with a first pair of rollers consisting of a first bottom roller (22, 42, 72) and a first top roller (21, 41, 71), wherein the drafting arrangement unit (35, 65 95) is configured as an assembly which is detachably fastened to the spinning machine by means of a fastening device (11, 59). The drafting arrangement unit (35, 65, 95) is preferably designed for one spinning station or as a twin drafting arrangement unit for two adjacent spinning stations. Said unit can also comprise further rollers which, together with the first pair of rollers, form a drafting zone of the drafting arrangement.

Abstract: In the donning and doffing operation of a spinning machine, a tube (20) is pushed onto a packaged tube (14), whereby the thread (7) remains unbroken. The package (14) and the tube (20) are rotated together, until a few turns of the thread (7) are wound on to the tube (20). The tube (20) is subsequently held and the packaged tube containing the package (14) is removed. Subsequently, the empty spindle (15) is guided into the tube (20) for subsequent spinning operations without the necessity for removing overwindings which normally occur.

Abstract: A thread receiving tube for use in a high speed thread spinning machine having rotatably driven spindles mounted on the machine for effecting thread spinning, the tube comprising a hollow tubular body including at least at its upper end a stabilizing member, which grips into an axial aperture in the top of the spindle, the member comprising longitudinal downwardly extending lips which engage the inside surface of the axial aperture of the spindle.

Abstract: The spinning device for open-end spinning comprises a withdrawal nozzle secured to a cover of a rotor housing for a spinning rotor and a nozzle body coacting with the withdrawal nozzle. The withdrawal nozzle and the nozzle body conjointly form a withdrawal passage or channel for the thread or the like produced by the spinning rotor. The cover is provided with a receiving socket which fixes the position of the nozzle body in radial direction, the nozzle body being inserted into the receiving socket. The nozzle body is pressed against the withdrawal nozzle by means of a manually-operable elastic device. The formation of the receiving socket permits insertion and removal of the nozzle body from the front side, that is from the service side of the spinning device. This provides the advantage of ready accessibility of the nozzle body and, in turn, thus affords easy replacement thereof. Replacement can be carried out without the use of tools.

Abstract: A sliver can transporting dolly comprising a base frame having substantially parallel longitudinal support beams and mechanism for laterally tilting, gripping underneath and lifting cans standing between the longitudinal support beams of the base frame.
