Abstract
An apparatus and method for producing brushes. The bristle bundles are loaded into a magazine which includes part of a cavity for an injection mold. The magazine is mated with the remainder of the injection mold and the brush handle injection molded around the bristles. The bristles may be profiled, trimmed, end-rounded, fused, or otherwise processed before the handle is injection molded. In addition, the handle of the brush may be formed in two injection molding steps of two different materials. An apparatus is taught which enables the brush to be produced, optionally ornamented, and packaged on a single machine.
