ABSTRACT:
A device for manufacturing brush products, in particular toothbrushes, with a bristle magazine having a feed chute for receiving filaments of precut length arranged in a dense array transverse to the longitudinal axis of the bristle magazine. The feed chute has a discharge opening which is bounded by a bristle picker closing the discharge opening from outside, and serves to feed filaments to a recess provided on the bristle picker. The recess receives only a predetermined quantity of filaments, combining them into tufts which are then transferred to further stations for further processing. According to the invention, the feed chute has a magazine bottom on which the discharge opening is formed. The magazine bottom is further shaped in an arcuate configuration tapering essentially in the direction of the discharge opening. This produces a steady filament flow in which dead zones are not allowed to develop.
