Abstract
A method of manufacturing flexible card-clothing for use in textile carding comprising the steps of producing a foamed polyvinylchloride compound having a density of between 0.6 and 1.00 grams per cubic centimeter; applying a sealing coat of a material which is compatible with the foamed compound to a fabric layer; applying a layer of the foamed p.v.c. onto the seaing coat to produce a finished foam layer of between 2 and 5 millimeters thickness on the fabric; heating the applied foamed layer to p.v.c. to cause the foamed layer to fuse; applying a surface layer of sealing material onto the exposed surface of the foamed layer to provide a smooth non-absorbent external surface, with the fabric, foamed p.v.c and surface layer together forming a composite foundation face, combining the foundation face with a foundation back to form a laminated foundation, and then inserting card-clothing wires into the foundation so that parts of the wires project from the surface layer.
