Abstract (en)
[origin: WO2005047578A1] The invention relates to a feed trough for a sliver opening device of an open-end spinning device, comprising a clamping area, which is actively connected to a sliver draw-in cylinder, for conveying a feed sliver, comprising lateral guide walls for guiding the feed sliver and comprising a concave supporting surface for fixing a tuft processed by an opening cylinder. The invention provides that the feeding trough (8) is designed and placed in its working position in such a manner that a gap width A between the supporting surface (13) and the adjacent tips (20) of the opening cylinder filleting (3) ranges from 0.7 to 1.5 mm at combing point K that continuously decreases to a gap width B of < 0.5 mm over an angular range W in a direction of rotation of the opening cylinder (2) of at least 30 DEG .
