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.

Apparatus and method for producing brushware by injection molding

A method and apparatus for feeding bristle bundle material into a magazine. The magazine is used in the production of brushes in which not all the bristle bundles extend in the same direction from the face of the brush. The feed apparatus for guiding the bristle bundle material from a supply to the magazine includes a number of transition plates having channels machined at an oblique angle to the surface of the plate. The plates each guide the bristle bundle material through a small angle; the assembled plates can guide the material through a large total angle so that the angle at which the bristle bundles enter the magazine is the same as the angle the bristles will have with respect to the brush.
