Fine-tooth clothing for the sliver loosening roller at an open-end spinner has an increased tooth interval for effective separation of stiff synthetic fibers without impact forces on them

摘要

The roller clothing with a fine tooth structure, for the sliver loosening roller to break it down into fibers for an open-end spinner, has a tooth interval (t) which is at least three times the tooth height. The cutting angle ( alpha ) is max. 10 deg . The tooth interval (t) is at least 4.5 mm. The cutting angle ( alpha ) is preferably max. 7.5 deg and the preferable tooth height is 1.5 mm. The point angle ( beta ) between the tooth cutting face (4) and the rear flank (5) is 30-40 deg . The flank angle between two tooth flanks is 8-10 deg .
