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.
