Abstract (en)

[origin: EP1176236A1] The sawtooth clothing, for a roller mantle, is a wire (56) in a spiral winding, with a blade section structured with triangular sawteeth. The wire blade section has a height of ≤ 2 mm and preferably 1.0-2.0 mm. The sawtooth clothing wire has triangular teeth (58) with a tooth height which is less than the height of the wire blade (60,62) section. The wedge angle ( beta ) of each tooth is 30-120 degrees and preferably 80 degrees . The cutting angle ( alpha ) of each tooth is (-) 20 degrees to (-) 60 degrees and preferably (-) 40 degrees . Each tooth has the shape of an equilateral triangle. The teeth are distributed at intervals (p) of 3-5 mm, with a larger tooth interval than the height of the wire blade section. An Independent claim is included for a filling shaft with a feed roller, fitted with a sawtooth clothing, to feed material to a carding machine with a productivity of ≥ 100 kg/hr. of sliver. The feed roller has a reversible drive.
