Abstract
The present invention relates to a device and a method for processing bristle filaments, in particular toothbrushes, with an abrasive surface. In order to improve, in particular, the processing of contoured brushes, the abrasive surface is formed according to the present invention on at least one tooth flank of at least one tooth which is provided on a rotating circumferential surface and circulates in the rotational direction. The method according to the invention is characterized in that the bristle filaments are moved in a first direction substantially in parallel to at least one tooth flank comprising the abrasive surface, and in a second direction substantially at a right angle to the first direction, over the ridge of the at least one tooth.
