摘要:
In order to grind clothing of a carding element, such as a cylinder of a textile machine, such as a card, during operation of the cylinder, a slide is moved back-and-forth across the clothing. The slide is reciprocated back-and-forth by an inner run of a drive belt guided in guides such that the drive belt together with a grinding element, like a grinding stone, closes a housing totally covering the arrangement. As a result, neither grinding dust nor fibers can enter the housing. Each time the grinding stone moves past a grinding member, such as a diamond rake or diamond roller this grinding stone is re-ground, so that the clothing is maintained sharpened by the continuous grinding operation and the grinding stone itself is cleaned or re-ground by the grinding member. Also, structure detects the degree of wear of the grinding element so that upon reaching a predetermined value such grinding element can be replaced.

A cylinder for a textile machine to be used as a licker-in, main cylinder or doffer has working clothing attached to the base structure. The clothing is attached in segments that have a regular geometric shape and a width less than the cylinder width. The segments are secured to the base structure so that the junctions, in the peripheral direction, are displaced from one another. Each segment is provided with a form locking edge to innerlock the segments in the cylindrical form.

The present invention is directed to a drawframe having a sliver delivery device and a computer part for maintaining a predetermined quality of sliver, wherein there is a predetermined overproduction from a card and/or a drawframe relative to a spinning machine. The arrangement temporarily decreases production to temporarily compensate for the overproductions. The sliver which is produced during the decrease in production may be delivered to a separate can.

The present invention is directed to a card having a sliver delivery device and a computer part for maintaining a predetermined quality of a carded sliver, wherein there is a predetermined overproduction from a card and/or a drawframe relative to a spinning machine. The arrangement temporarily decreases production to temporarily compensate for the overproductions. The sliver which is produced during the decrease in production may be delivered to a separate can.

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.
摘要:
A method and apparatus for cleaning or carding textile fibers between a fine cleaning or carding drum (2) with clothing (7) fixed thereon and carding elements (5) surrounding said drum, a clothing (9, 10, 11, 12, 13, 14) also being provided thereon. The teeth (9, 10, 11, 12, 13, 14) of the carding elements (5) are so provided differently in the direction of movement (8) of the rotating drum (2) that the tooth (9), for example, has what is known as a negative carding direction with a relatively large angle (.alpha.) and the tooth (14) a positive carding direction with a relatively small angle (.alpha.) and the teeth therebetween have different attack angles as shown in FIG. 3. This gives different cleaning or carding effects within a predetermined peripheral zone of the drum.

Individual fiber components are blended in accordance with the properties of a required intermediate product such as a card sliver or an end product such as a yarn. The fiber bales are combined into component groups and the fiber components in the groups are accurately supplied by metering devices to a blender in which the components are uniformly mixed. The product from the blender may be cleaned and thereafter carded into a sliver. The characteristics of the sliver, such as the color, fiber, fineness and quantity, are tested and adjustments made in the blending in dependence upon any deviation from preset values for the characteristics.

A carding machine is provided with a built-in clothing grinding system which can move a grinding element from a waiting position over the processing width of a carding machine, with a control unit being provided for controlling the work of the grinding element.
摘要:
A carding element (3) on the periphery of a carding or cleaning roller (1) is arranged to be movable in the direction toward or away from the roller (1) and is movable to selectively present different types or sizes of clothing elements (14.1, 14.2, 14.3 and 14.4) in proximity to the roller (1) so as to effect different actions on the fibers as the clothing elements on the carding element function as counter clothing elements for the clothing (12) of the carding or cleaning roller. This facilitates optimization of the cleaning function obtainable through the cooperation between the clothing (12) on the card drum and the clothing elements (14).
摘要:
A fiber infeed device supplies fiber material to a textile machine, such as a card, and comprises a driven rotatable feed roll and feed plate. This feed roll is, however, spatially fixed, whereas the feed plate is pivotable but physically immobile during detection of the thickness and thickness variations of the infed fiber material. The feed plate can be pivoted into an operating position against a stop during throughpass of the fiber material. A substantially invariable size nipping zone is thus formed between the driven rotatable feed roll and the stationary feed plate in which a property of the throughpassing fiber material representative of its instantaneous thickness and thus variations thereof can be detected. By positionally fixing the feed plate, for instance, different forces are applied thereto in the nipping zone where the fiber material is compacted. The arising variable forces enable ascertaining thickness variations of the infed fiber material. A further aspect contemplates deriving from the variable forces control signals delivered to a control device for comparison with a predeterminate reference value signal to produce output signals for controlling the rotational speed of the feed roll and thus compensating thickness variations of the infed fiber material.
