Abstract: A spinning frame of the type having a main drafting zone through which two fiber bands move in spaced parallel relation for subsequent twisting into a single yarn is provided with a first pair of rollers located at the entrance to the main drafting zone, a second pair of rollers located at the exit of the main drafting zone, a pair of endless leather tapes extending about a roller in each of the first and second pair of rollers, and a third pair of rollers for delivering two fiber bands from the main drafting zone to a suitable twisting device.

Abstract: The invention relates to a spinning or twisting machine with a plurality of upright textile spindles, wherein the spindle shaft of each textile spindle is coaxially firmly attached to the rotor shaft of an electromotor and wherein the housing of the electromotor includes upper and lower bearing brackets that are disposed on a spindle rail and for the purpose of simple and precise centering of the electromotor housing these bearing brackets are radially adjustable on the spindle rail independently of one another.

Abstract: A new ring rail having air-suspended spinning or twisting rings suspended in air bearings is proposed, the improvement residing in that an intermediate ring is releasably connected to a bearing stator in an outer ring and thus can be quickly exchanged at any time.

Abstract: A wrap-winding spinning machine for producing wrapped yarns having draw frames for attenuating slivers, wherein one wrap-winding apparatus is associated with each draw frame is proposed, with the wrap winding apparatus further including a high speed rotor and a yarn channel coaxial with the axis thereof, the rotor associated with a driven hollow spindle and a bobbin supported thereon and a balloon limiter supported on the machine frame by upstanding opposed ribs. The bobbin supports a centrally apertured cap device with the cap device having a continuously curved, convex end face with a sharply curved rim that merges with the end disc of the bobbin. The aperture in the cap device is arranged to receive the feed of the winding thread and the sliver as it passes downwardly into the yarn channel and is emitted as a finished wrapped thread.

Abstract: A method of producing a mountable tube for use with a textile spindle and the article produced by the method is revealed herein. The mountable tube is produced by cylindrical hammering of a steel body which may be provided interiorly thereof with a perforated insert body incapable of being deformed under the hammering process, but capable of being held within said mountable tube subsequent to completion of the hammering operation. The insert body is arranged to support the mountable tube on the textile spindle.

Abstract: A false twisting machine which includes a frame having racks of thread supply spools on opposite sides with centrally disposed bobbin supporting take-up mechanisms therebetween defining corridors on opposite sides thereof with thread heaters and false twisting members disposed horizontally across the top of the machine, together with thread transport mechanisms for stretching the threads and for advancing the threads vertically upward from the thread supply spools on opposite sides of the machine across the top of the machine in a horizontal path with virtually no deviation therefrom through the heaters and false twisters and then downwardly onto the take-up bobbins for ultimate removal of the wound thread packages from the machine thereby providing a machine of greatly reduced height and capable of easy maintenance.
