Problems solved by technology

However, the fineness of shaving is compromised by the fact that the blade always only cuts on one side and therefore a part of the contact between the blade and the hair cannot lead to a shortening of the hair

Embodiment Construction

[0017] figure 1 A schematic cross-sectional view showing several parts of an embodiment of a cutting head for a shaver constructed in accordance with the invention. Shown is the lower blade 1 and the shaving foil 2, to which the lower blade 1 is adjacent. The cutting planes selected for the illustration are parallel to the direction of relative movement between the lower blade 1 and the shaving foil 2 , which are each shown in section. The lower blade 1 has a plurality of cutting edges 3 arranged in a regular sequence. Each cutting edge 3 provides a first cutting edge 4 and a second cutting edge 5 which are respectively arranged on mutually opposite sides of the cutting edge 3 . The geometry of Blade 3 is in figure 2 shown in detail.

[0018] The cutting edges 4 and 5 are each aligned in such a way that two first cutting edges 4 and two second cutting edges 5 respectively follow each other alternately in mutually consecutive cutting edges 3 of the lower insert 1 . This m...

Abstract

The invention relates to a lower cutter (1) for a razor head driven in an oscillatory manner. Said lower cutter (1) comprises a plurality of blades (3) that are respectively grouped into pairs of adjacent cutting edges (3), first cutting edges (4) for cutting hairs (9) being embodied on facing sides of the blades (3). The inventive lower cutter (1) is characterised in that second cutting edges (5)for cutting hairs (9) are embodied on opposing sides of the two blades (3) of a respective pair, said second cutting edges cutting less than the first cutting edges (4).

Description

technical field [0001] The present invention relates to a lower blade for an oscillatingly driven cutter head of a shaver. Furthermore, the invention relates to an oscillatingly driven shaver head with such a lower blade and a method for cutting hair. Background technique [0002] The lower blade of the oscillatingly driven head of the shaver is designed to work with the upper blade to cut hair. The lower blade thus performs an oscillating relative movement in a direction parallel to the upper blade and in this case presses the upper blade with a certain pressing force. The upper blade is designed, for example, as a perforated shaving foil, which has a plurality of hair entry openings. Since through the hair entry opening both hair and skin parts can reach the effective range of the lower blade, there is a risk of skin irritation or almost cut injuries due to contact with the lower blade. [0003] In order to avoid the above-mentioned adverse effects, it is proposed in JP...
