A handle for use in production of brushes by fusion. The handle is injection molded with a set of pre-formed holes. Each hole contains, on its bottom surface, a protrusion of excess material. Bristles for the brush are heated to form a small fuse at their ends. When the fused ends are inserted into the holes, material from the protrusion flows around the fuses, retaining them in the holes upon cooling.

Handle configuration for brush production by fusion

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.
