ABSTRACT:
A long ribbon, composed of a multitude of fine wires, is placed at the requisite bristle angle onto a backing ring. A torch, welds the ribbon to the backing plate and simultaneously severs the ribbon--forming a first bundle of wires. The severed ribbon is repositioned, relative to the backing ring, adjacent to the first bundle, and the ribbon is again welded in-place and cut. The procedure of placement, welding and cutting is repeated until the backing plate (or the ribbon) has been repositioned over the desired length of the plate to achieve the requisite bristle array of the brush seal.
