CARD CLOTHING

摘要

Card clothing which can be applied to a roller for use in a fibre carding process comprises a backing web and an array of carding needles which are embedded in the web. The card clothing has a machine direction axis defined by the edge of the backing web and a transverse axis perpendicular to the machine direction axis, and the carding needles are provided in the web in parallel rows and the rows are arranged so that they are not parallel to the transverse axis of the card clothing. Each of the carding needles comprises an upstanding portion which extends from the surface of the web, and a cranked portion towards its tip which extends generally along the machine direction axis of the web, the upstanding and cranked portion defining the needle plane, and the needles being arranged on the web so that the needle planes are not parallel to the machine direction axis.
