Abstract
Abstract A device for improved carding having a concave support with a curvature corresponding to the curvature of a main cylinder includes a plurality of segments or bands of wire having a predetermined concave reverse curvature therein, so that sides opposite base portions of the bands face inwardly. A plurality of the reverse curved segments are positioned in adjacent rows in alignment on the support with teeth on the sides of the bands opposite the base portions facing inwardly. The segments are fastened on the support as by clamping. The segments have a curvature corresponding to the curvature of the concave support by virtue of a reverse set prior to being fastened on the support.

Total Claims: 3
Claim 1
Independent Claim
151 words
Wire card clothing comprising: A. a circumferentially curved enlarged metallic wire base portion having a predetermined reverse curvature therein corresponding generally to a main carding cylinder; B. a curved outer portion of said wire base portion having a curvature corresponding thereto; C. a curved inner teeth carrying portion of said wire base portion opposite the outer curved portion and having a curvature corresponding thereto; D. spaced inverted carding teeth of such configuration as to avoid loading carried integrally on said curved teeth carrying portion projecting inwardly; and E. the curvature of said wire base portion, said curved outer portion and said curved inner teeth carrying portion being therein by a set having been placed therein, whereby said inverted teeth may be disposed in carding relation toward the teeth of clothing of a main carding cylinder so that carding occurs continuously over substantially an entire carding surface defined by said inverted teeth.
