METHOD OF MANUFACTURING FUSED BRUSHES Abstract of the Disclosure A method for manufacturing synthetic brushes comprising synthetic filament fused directly to a synthetic polymer substrate is disclosed. A plurality of brush backs are formed integrally on a frame. The brush backs are then held stationary while a picking plate having a plurality of pickers, in a design of brushes, is indexed into a stock box and filled with tufts of synthetic filaments. The picking plate is then indexed out of the stock box and into a heated plate to fuse the ends of each tuft. The picking plate with tufts is then indexed into the frame-holding means whereby each of the fused ends is simultaneously mounted on each of the brush backs. In this way, a plurality of brushes are simultaneously formed. The brushes may then be packaged on the frame or individual gates severed to permit packaging of individual brushes.
