Abstract (en)
[origin: EP1473388A2] The device comprises, at the outlet of the final pair of rollers (4) of a spinning machine draw-frame, a tubular element (20) which is parallel to the axis of said rollers (4), is connected to a source of vacuum, and is provided with multiple transverse grooves (7), on which there runs a band (9) provided with small perforations for receiving, in turn, through its face remote from said tube, the sliver (5) leaving the draw-frame, and performing the transverse condensing of said sliver (5) as it adapts to the empty grooves (7) through the perforated band (9), the tubular element (20) having a gently curved structure in the adaptation region of the perforated band (9), and is characterised in that it comprises a drive cylinder (13) inside the perforated band (9), which receives a tangential upper roller (14), which has resilient characteristics and of which the drive cylinder (13) is actuated by a longitudinal shaft common to the various drawing units of the machine. <IMAGE>
