摘要:
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.

A carding machine includes a main carding cylinder having a circumferential surface carrying a cylinder clothing thereon; and a cooperating with the main carding cylinder. The traveling flats assembly includes a plurality of clothed flat bars arranged in a series and a flat drive for moving the clothed flat bars in an endless path having a working path portion along which the flat bar clothings cooperate with the cylinder clothing and a return path portion; and a grinding assembly for sharpening the cylinder clothing. The grinding assembly includes a grinding flat bar adapted to be positioned in the series of clothed flat bars to be moved by the flat drive in unison with the clothed flat bars; and a grinding element mounted on the grinding flat bar. The grinding element is in a contacting relationship with the cylinder clothing along the working path portion of the traveling flats assembly.

A fiber processing machine includes a fiber processing component and a material-removing roll supported to be in contact with the fiber processing component for removing material therefrom. The material-removing roll includes a radially deformable resilient circumferential surface and a material-removing substance carried at least indirectly by the resilient surface.

A card clothing is mounted on a support and rotatable therewith about an axis. A grinding apparatus for the card clothing has an abrasive grinding element, a base juxtaposed with the card clothing, and an elastic biasing element for pressing the grinding element radially of the axis against the card clothing so that when the support and card clothing are rotating the element grinds the card clothing. The grinding element is displaceable radially outward away from the card clothing against a force of the biasing element from a grinding position engaging the card clothing to a rest position out of contact with the card clothing. The apparatus has a mechanism for withdrawing the grinding element against the force of the biasing element into the rest position and for retaining it in the rest position. An abutment is provided furthermore for defining a position of closest approach of the grinding element to the axis and hence, how much it will grind down the card clothing.

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.

The method of grinding the teeth of metallic card clothing on a roll of a textile carding machine contemplates positioning an abrasive grinding surface in substantially stationary grinding relation substantially entirely across a segment of the card clothing on the roll so that said grinding surface conforms generally to and engages the teeth of the card clothing, and imparting rotation to the roll causing the grinding to result substantially entirely from the rotation of the teeth with respect to the stationary grinding surface.
