Abstract:
To optimize the cleaning of cotton in a spinning milk, there is entered into a control original data concerning fiber characteristics and proportions of different types of contamination inherent to the origin of fiber cotton bales. Also there is entered into the control a desired degree of cleaning and a throughput quantity of the carded fiber sliver. The control delivers predetermined control signals based upon the entered original data, the throughput quantity of the carded sliver and the desired degree of cleaning. These control signals set adjustable operating members governing the rate of opening of the cotton bales by bale opening machines, the degree of cleaning of the cotton fibers by cleaning machines and the rate of processing of the cotton fibers by at least one carding machine.
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:
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 card is equipped with a regulating drafting system at the card delivery arrangement. The measuring values for regulating the drafting system are obtained from the drafted fibre sliver. The sliver depositing device can be pre-controlled relative to the drafting system in order to keep the stresses in the fibre sliver between the drafting system and the sliver depositing device within limits. A fibre sliver storage device (11) is arranged upstream from the regulating drafting system (13) with relatively small capacity. In order to enable timely action if long term deviations are detected in the fibre sliver mass (m) delivered, a sensor (10) can be arranged between the card (1) and the regulating drafting system (13), and the base rotational speed (U14) of the drive (25, 26) of the regulating drafting system (13) can be adapted based on signals transmitted by the sensor (10).
Abstract:
A device for grinding clothing teeth and wire, or for cleaning cylinders, in a textile machine includes a grinding part having an elastic layer and grinding elements embedded throughout the elastic layer. The elastic layer is formed into a shape for being pressed against the clothing teeth, wire, or cylinder of the textile machine, and is formed of a material such that the elastic layer is worn by the clothing teeth, wire, or cylinder. In this way, the underlying embedded grinding elements are exposed.
Abstract:
In a plant for processing textile fibers, the fine cleaning is effected at a point at which the stream of fiber material already has been subdivided (e.g. for the subsequent carding process), e.g. in the card filling chute. The cleaning device comprises at least one separating element arranged above the transporting roll. The trash eliminating system includes a system for eliminating material separated from the zone of the roll.

Abstract:
The present invention relates to the application of fiber length measurement in the blowroom or carding room of a spinning mill. A method and an apparatus in a textile processing machine are described in which before and/or after a working element of the textile processing machine the nep count and/or the fiber length (staple) is determined, with an open-loop/closed-loop control unit being provided which receives the values for the fiber length and/or the nep count as input and determines therefrom the optimized machine setting data and outputs the same to at least one actuator of a working element which influences the nep count and/or the staple of the textile processing machine.
Abstract:
A system is provided for processing textile fibers. A bale plucker removes fiber flocks from bales of fiber material and a flock transporting system delivers the flocks from the bale plucker to a carding machine or other processing apparatus. A feed chute is configured with the card machine and includes a first part for receiving flocks from the flock transporting system, and a second part for delivering a fiber lap to the card machine. A cleaning device is disposed within the feed chute between the first and second parts. The cleaning device comprises a fine cleaning nip feed arrangement. This nip feed arrangement in the feed chute is the only fine cleaning nip feed arrangement within the system between the bale plucker and the cleaning device.
