Method and device for producing brush products

Image Number 3 for United States Patent #6578927.

A multi-stage injection molding method for the brush body is proposed in the first injection stage of which sealing of the bores of the bottom plate of the injection molding tool, including the tips of the cords of bristles that protrude into the mold interior is performed, and with the opening of the injection molding tool, a zone of rigidly fastened cords of bristles is created between the brush body, fastened in the intermediate plate, and the bottom plate, so that the cords of bristles can subsequently be served in the open without a counterpart blade, using a severing knife that swings back and forth, without the need for remachining the cut faces.
