Method of bristle insertion for brush production
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.
