Title:
METHOD FOR PRODUCING A TOOTHBRUSH HEAD
Document Type and Number:
WIPO Patent Application WO/2012/011084
Kind Code:
A3
Abstract:
The present invention relates to a method for producing a brush head (4), in particular a toothbrush head of an electric toothbrush (1), in which bristle tufts (11,13) that are already fixed to a bristle support of the brush head are cut at the free ends thereof such that a desired tuft end contour is generated. According to the invention, at least one bristle tuft (11) is bent away at least in parts and held in a bent-away position while the tuft end contour of this at least one and/or of another bristle tuft is cut. In this way, the adjacent bristle field portion does not hinder the processing of the respective bristle field portion, thus enabling in particular the creation of more angular or more complicated tuft end contours, where the cutting tool, which must be held appropriately inclined, would otherwise cut into adjacent bristle field portions. First and foremost, however, the deflection of the bristles to be cut makes it possible to achieve other cutting geometry proportions that make more inclined and/or more curved bristle end contours possible, without cutting the ends of the individual bristles too pointed.
