Card for processing fiber materials, comprises card clothing with comb structure carried by underlay and fitted to carding-flat bar in release mounting for easy exchange

摘要

The card, with a card clothing to bring fibers (2) into parallel, has a card clothing (8) with a comb structure (10) which is mounted to each carding-flat bar (7) by a fastening with a reversible release. The card clothing is mounted to a rigid underlay, which is fitted to the carding-flat bar by a release mounting. The underlay is of sheet plate, to hold the clothing by an adhesive or fastening screws. The clothing underlay has projecting bars at the side edges, to fix the card clothing at the sides. The underlay and projecting side bars form a one-piece unit. The underlay, with the card clothing, lies on the upper side of the carding-flat bar to be held in place by buckles. The buckles have upper and lower projections where the upper projection is over the clothing underlay and the lower projection is at a shoulder of the carding-flat bar. The buckles are rail sections, with a buckle extending over the length of the carding-flat bar or the card clothing fitted to it. A number of buckles can be fitted in succession along the carding-flat bar and the mounted card clothing. The buckles are shaped from sheet plate. The underlay, with the card clothing, can be secured to the carding-flat bar by an adhesive or fastening screws, and it can be pushed within a guide at the bar as a swallowtail groove.
