Fibre-opening device for open-end rotor spinning machines

摘要

The subject of the invention is a fibre-opening device for open-end rotor spinning machines, in which the removal of the fallen-out fibres from the fibre-feed space occupied by the feed roller (9) and the pressure bowl (10) is optimised. According to the invention, there are provided on both sides of a feed surface (16) for the fibre sliver, along the end walls (6, 7) of the cylindrical cavity (4) of the opening housing (2) and opposite the opening roller (5), longitudinal recesses (22) which connect the fibre-feed space to the cleaning orifice (13) and to the dirt-removing channel (15).
