摘要： For an air spinning frame, reluctance motors are provided for each spinning place to drive the pairs of rollers of the drafting unit, the drawing-off means, and the friction roller. Thereby, for the run-up of a spinning place, e.g., after a thread break, a specific frequency converter is provided. After reaching the stationary operating speed, a switch over onto a further frequency converter takes place, at which time, the corresponding reluctance motors of the other spinning places are driven in parallel. By the use of reluctance motors it can be done without a complex speed regulation means. A specific dimensioning of the reluctance motors permits a very fast run-up and a particularly good efficiency during the stationary operation.

摘要： A top roller unit is arranged on a top weighting arm for a drafting apparatus of a spinning machine, which top roller unit has a holding device and two double top rollers and is arranged at two adjacent spinning stations. A first top roller of a spinning station borders a drafting zone which serves to draft a fiber strand, and a second top roller of a spinning station borders a condensing zone which serves to condense the fiber strand and which is arranged downstream of the drafting zone. The second top roller of each spinning station is driven via a drive by the first top roller, which drive takes the form of an intermediate gear which is common to all the top rollers of the top roller unit. The top roller unit is supported by a housing which encapsulates the intermediate gear.

摘要： An endless transport belt transports a drafted fiber strand through a fiber bundling zone. The transport belt is provided with a perforation for a suction air stream which suctions the fiber strand. The transport belt is provided with a sufficiently smooth surface for sliding over a suction device. The transport belt can be in the form of an endless woven or knitted sieve belt or alternatively in the form of an extruded plastic apron having punched out holes.

摘要： A condensing zone for condensing a drafted, still twist-free fiber strand is arranged downstream of a front roller pair of a drafting unit of a spinning machine. An air-permeable transport belt transports the fiber strand through the condensing zone. The transport belt slides hereby over a stationary sliding surface, in which a suction slit of a suction channel is located. At the end of the condensing zone, the fiber strand is pressed with the transport belt by a nipping roller to the sliding surface. The nipping roller as well as the front pressure roller of the drafting unit are supported in a top weighting arm. A separate pressure spring is arranged each for the top pressure roller and for the nipping roller. It can be provided that the nipping roller is arranged at a holding device, which can be swivelled around a swivel axle, which lies coaxially to the axle of the front pressure roller.

摘要： A condensing zone for condensing a drafted twist-free fiber strand is arranged downstream of a drafting arrangement of a ring spinning machine. The condensing zone includes a stationary sliding surface having a suction slit extending essentially in a fiber strand transport direction. A perforated transport belt transports the fiber strand over the suction slit of the sliding surface. The transport belt wraps around a bottom roller of a front roller pair of the drafting arrangement and is driven by the bottom roller. The transport belt drives in turn a nipping roller, which limits the condensing zone on its exit side with a nipping point serving as a twist block. The nipping roller presses the fiber strand and the transport belt against the sliding surface of the condensing zone.
