Abstract: 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.

Abstract: Textile fiber carding apparatus is provided with an adjusting system for carrying out linear adjusting movements which are at least esentially independent of friction, and free from jerks and oscillations. The system includes a carrier (20) for the object (12) (e.g., the doffer) to be adjusted and an actuating mechanism (40) in contact with the carrier. The carrier (20) is supported at at least two positions spaced apart from each other in the direction of adjustment on respective supporting devices (26, 26.1). At least one of the supporting devices is formed by a generally cylindrically shaped bellows (28) filled with a bubble free incompressible fluid and is secured at its one end face to the carrier (20) and at its other end face to a foundation (24). At least one flat spring (34, 34.1) is secured at its one end to the foundation (24) and its other end to the carrier (20). One or more addition supporting devices (26, 26.

Abstract: 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.
