Abstract
A brush structure for use as a stitch support for a velour needle loom comprises bristle tufts inserted into a carrier plate, with their free ends forming a continuous support surface for supporting thereon a fiber batt to be needled. The foot portions of the bristle tufts are of polygonal cross-section, resulting in a high packing density of the bristle tufts on the carrier plate and optimum bristle-coverage thereof. This enables excellent continuity of the support surface formed by the free bristle ends to be achieved without the bristles having to be provided with a curl or crimp.
