    摘要: A concave metallic surface suitable for carding and the like is applied to a concave support by placing a predetermined concave reverse set curvature in a band of wire so that teeth on a side of the band opposite a base of the band face inwardly, cutting a plurality of concave segments from said band, positioning the concave segments in adjacent rows in alignment on the concave support with the teeth facing inwardly away from the support, and fastening the segments on the support as by clamping.
