摘要： Dirt is initially removed by means of blown air (RD) in a fibre-processing machine (30) that is provided with a separating edge (24). Fibres and air are conducted in a substantially predetermined direction of conveyance on said edge and a layer of air that is loaded with dirt particles or refuse is deflected from the fibre/air flow (10) by means of the separating edge.

摘要： The invention relates to a spindle (10) for an air jet spinning machine, which comprises an injector channel (1) leading to the immediate vicinity of the spindle opening (8), thereby allowing to return (B) the yarn end when the spinning process was interrupted. In order to return the yarn end, pressurized air is supplied through the injector channel (1) and generates a suction effect at the spindle end (11). Once the yarn end is returned (B) to the level of inlet of the injector channel (1) into the yarn guiding channel (5), the pressurized air blows out the yarn end from the spindle opening (8).

摘要： The invention relates to a winding head (1) for winding a spun thread (2) on a reel (3) or on a bobbin tube (4), wherein said winding head (1) is provided with a friction roller drive (5) for driving the reel (3) and a cross-winding device (7). Said invention is characterised in that the cross-winding device (7) is driven by the reel (3) by means of a slipfree preferably frictionally engaged drive transmission (8), wherein said drive transmission (8) of the cross-winding device (7) is designed in such a way that a winding ratio is constant, thereby making it possible to obtain a precision reel.

摘要： The invention relates to a card which at the level of the card doffer (7) has an optoelectronic device (20A; 20B) for monitoring the quality of the lap. The device (20A) can be at a distance (S) of at least 20 mm to the housing surface (7A) of the card doffer (7) to ensure that the lap quality is not affected by the device itself. Alternatively the device (20B) can be assigned to a lap guiding element (16) which independently of said device carries out a function related to the processing and/or transport of the lap.
