Abstract
Method of manufacturing a blade-shaped hair-pulling element ( ) for a cutting unit ( ) of a shaver. The shaver comprises a plurality of cutter elements ( ) and a corresponding plurality of hair-pulling elements ( ) each arranged in front of one of the cutter elements for movement therewith relative to an outer cutting member ( ) and each slidable on the inner cutter element so as to be movable relative thereto for its hair-pulling action. In order to increase the distance over which the hairs are pulled up, an end portion ( ) of each hair-pulling element ( ) has an enlarged thickness. The hair-pulling element is obtained by means of a process of shaping the outline (stamping, etching, laser) followed by a bending process. The method to obtain the thickened end part ( ) is characterized in that during the process of shaping the outline, the hair-pulling element is provided with a tab ( ) which in a following bending process is bent against the end portion ( ) of the hair-pulling element.
