Abstract
A flat composed of a flat body with a flexible covering fastened thereto and having a plurality of outwardly extending card wires distributed across the covering, for use in carding machines, is produced by disposing such a flexible covering against the outer surface of a cylinder with the outwardly extending wires directed toward the cylinder surface, the outer surface of the cylinder being shaped to define the desired contour of the array of card wire tips; pressing the flexible covering against the outer surface of the cylinder for causing the array of card wire tips to conform to the shape of the outer surface of the cylinder; disposing an associated flat body at a distance from that surface of the covering which is directed away from the cylinder; and filling the region between the flexible covering and the rigid body with a hardenable plastic mass and permitting the mass to harden and to become firmly attached to the flat body and to the covering.
