Abstract
A fixed tube of circular cross-section, which is common to several spinning stations disposed side by side, is connected to a suction source and has, in each station, a suction slot arranged on the path of a bundle of fibres to be compacted and along its direction of advance. A cylindrical sleeve is freely rotatable on the tube and has a perforated portion which extends around a corresponding slot. The sleeve is rotated about the fixed tube by a pressure roller which presses the bundle of fibres against the perforated portion of the sleeve. The sleeve cooperates with an axially stationary retaining element which is separate from the tube and is arranged to limit the axial movements of the sleeve along the tube.
Claims22
A compacting unit for compacting a bundle of textile fibres coming from a drawing unit in a spinning station of a spinning machine, of the a comprising:
- a fixed tube of circular cross-section which is common to several spinning stations disposed side by side and is connected to a suction source and which has, in each station, a suction slot arranged on a path of the bundle of fibres and along the fibres direction of advance,
- at least one cylindrical filtering sleeve freely rotatable on the fixed tube and having at least one perforated portion which extends around at least one corresponding slot, the sleeve being rotated about the fixed tube by a pressure roller which presses the bundle of fibres against the perforated portion of the filtering sleeve,
- wherein the sleeve is adapted for cooperating with at least one stationary retaining element which is separate from the tube and limits the axial movements of the sleeve along the tube.
