Embodiment Construction

[0017] The rotor spinning device 1 comprises, in a manner known per se, a spinning cup 2 which rotates at high rotational speed in a spinning cup housing 3 which is under vacuum. The spinning rotor 2 is supported and driven in a manner not shown in detail. The support can be realized, for example, by two pairs of support discs, and the drive of the spinning rotor, for example, by a tangential belt. The monofilaments produced by the opening roller 4 in a manner known per se are conveyed via the fiber conveying channel 5 to the spinning rotor and spun into a yarn 6, which is conveyed in the direction of the arrow A via a doffing channel 7 to a not shown network. yarn device.

[0018] The opening roll 4 is connected to the drive roll 9 via a shaft 8 and is rotatably supported on a supporting structure 10 . The drive roller 9 is assigned a tangential drive belt 11 running longitudinally through the machine, which drives the opening roller 4 to rotate. The rotating opening roll ...

Abstract

The invention relates to an air spinning device having an opener roller mounted in a pivoted shell. The open roller is provided with a brake device comprising a block brake for exerting the elasticity. When the shell rotates, the block brake automatically breadthwise feeds to the transmission roller of the opener roller by the elasticity and generates contact therein. The brake device is configured to form the holder of the pivoted shell at the same time. The brake device and the holder may comprise a common lever mounted with the block brake and the holder acted on part of the fixed frame.

Description

technical field [0001] The invention relates to an air spinning device with an opening roller mounted in a rotatable housing and a braking device assigned to the opening roller, which comprises a brake shoe brake block exerting elastic force, wherein, at When the housing turns, the brake shoes are automatically fed across the opening roller by elastic force and make contact there. [0002] Furthermore, the invention relates to a lever for a brake of an opening roller on an air spinning device and a brake shoe for such a brake. Background technique [0003] German laid-open document DE 23 23 511 discloses an open-end spinning device with an opening roller brake, on which the invention is based in the preamble. In the disclosed braking device, there is a lever, which is loaded by a pressure spring, on which the brake shoe brake block is fixed. The lever with the brake shoe is actuated by an additional operating lever supported on the fixed frame of the air spinning device. ...
