Abstract: A grinding device for the flats of a card comprises elastically bendable elements which enter between the clothing points, brush over the side flanks of the points and thereby grind the points. Additional grinding elements are provided in order to treat the front sides of the clothing points. The ground-off material may be removed by a suction device.

Abstract: A machine (28, 201, K, 400) for processing textile material with at least one sliver-forming device (209, 41) and a coiler (42, KA) is provided with a drafting arrangement (2, 110, 213) in such a way that at least the coiler (42, KA) is formed by a subassembly of a draw frame (1, S) for doubling and drafting slivers (40, F, 52, 120), with the subassembly (1, S) also comprising the drafting arrangement (2, 213) of the draw frame.

Abstract: The object of the invention is to facilitate the entry of a fiber band into a drawing machine. The invention is comprised of a fiber band insertion apparatus having a combination condenser and guide device with a longitudinal slot extending over its entire length. The guide device is followed by roll pair, which, at least during the laying in of the fiber band, has an accessible entry opening. This opening is at least partially formed by a recess in at least one of the opposed sides of the roll pair. The recess is separated by a flange on one of the circumferential rim surfaces which are mutually profiled to provide space for a compression line for the fiber band. The entry opening of the roll pair and/or feeders, as well as the entry slot of the condenser are, essentially, arranged in a common plane. With the aid of the invented apparatus, the fiber band is laid into the band entry device by a movement transverse to the normal transport direction of the fiber band when the drawing machine is running.

Abstract: The present invention concerns a drafting system (30) with a drive (M2) provided with a regulating device (M3, 33) for levelling out mass variations in a fiber mass (6) supplied to the drafting system by a supply source (1). The mass variations are detected by at least one measuring sensor (70) coordinated to the drafting system and the corresponding signals are transmitted to a control unit (S). A further device (11, 12, 62, 63) may be coordinated to the drafting system (30) which is suitable for detecting differences between the delivery speed of the supply source (1) and the intake speed of the drafting system (30) and apply it for influencing the base rotational speed of the drafting system or to detect long term mass variations from a predetermined desired value in which arrangement these mass deviations detected are applied for influencing the base rotational speed of the drafting system.

Abstract: The main drum diameter (D) of a card for short staple carding is reduced. The working width preferentially is enlarged. The main drum (50) can be made from fiber reinforced synthetic material. Notwithstanding its smaller diameter, the new main drum is operated at the same or a somewhat higher circumferential speed (in comparison to a conventional card).

Abstract: A stretched fiber band is deposited in a can, located in the filling station of a can exchanger of a draw frame, by means of a turntable. The rotational axis of the turntable exhibits an equal to or less than distance from the rotational axis of the can exchanger than the distance from the center point of the can found in the filling station to the rotational axis of the exchanger. Upon the substitution of the filled can by an empty can held in a ready-state position, the operation of the can exchanger on the rotation of the turntable is designed in such a manner, that the fiber band is deposited into the full can exiting the filling station, until this can leaves the zone of the turntable. The fiber band is then deposited into the empty can which has been brought into the filling station II, as soon as this empty can reaches the zone of the turntable.

Abstract: In a fiber processing machine with a separating edge in which fibers as well as air are guided in a substantially predetermined transporting direction past the edge, trash particles are selectively removed from the fiber/air stream with the help of the edge. The adjustment of a separating element, in particular, the setting of the angular position of a separating surface and/or the penetration depth upstream from the separating surface is linked with an adaptation of the width of the eliminating gap. Also, at least one measure can be taken for eliminating, as far as possible, a pressure drop and/or air turbulences downstream (in the transporting direction) from the edge. Downstream from the edge, a flow pattern as laminar as possible is generated or maintained, respectively.

Abstract: A grinding apparatus for the flats of a card comprises elastically bendable elements which penetrate between the points of the flat clothing sweep along the lateral flanks of the flat clothing wires and grind the points in the process.

Abstract: A flat of a revolving flat card is provided with a clothing the points of which are subdivided into groups. The flat preferentially presents an area provided with clothing of a length of more than 1000 mm. The groups each may present a "heel", or a clothing plane each respectively, facing the main drum. The groups can be formed by respective clothing strips (flexible clothing) fastened on a support member to extend in the longitudinal direction thereof, or by saw tooth wire strips (metallic card clothing) arranged side by side and extending in transverse direction of the flat.
