Patent ID: 8651582

Claim:
A method for producing a brush head of a toothbrush, the method comprising the steps of: a) providing bristle tufts that are fixed to a bristle support forming a bristle field of a brush head; b) cutting the bristle tufts at their free ends such that a tuft end contour is generated by bending away at least in part at least one bristle tuft and holding the at least one bristle tuft in a bent away position while the tuft end contour of the at least one bristle tuft of a second bristle tuft is cut; and c) cutting a depression having a groove-shaped bottom in a central section of the bristle field of the brush head, the depression being arcuately curved in one direction and straight in a direction perpendicular thereto, the groove-shaped depression being cut by: i) a first cutting tool having a first diameter and a first direction of rotation, the bristle support being moved in the direction of a longitudinal extension of the bottom of the groove-shaped depression relative to the first cutting tool or the first cutting tool being moved in the direction of a longitudinal extension of the bottom of the groove-shaped depression relative to the bristle field; and ii) a second cutting tool having a second diameter different than the first diameter, and a second direction of rotation opposite the first direction of rotation, the bristle support being moved in the direction of a longitudinal extension of the bottom of the groove-shaped depression relative to the second cutting tool or the second cutting tool being moved in the direction of a longitudinal extension of the bottom of the groove-shaped depression relative to the bristle field.
