Definitions
- the invention relates to a dry shaving apparatus with at least one shaving head consisting of an upper knife and a lower knife, the upper surface of which has a contact surface and a slot and webs.
- at least one shaving head consisting of an upper knife and a lower knife, the upper surface of which has a contact surface and a slot and webs.
- at least one further wall element that is angled and assigned to this wall element, wherein threading elements are provided on the wall element forming the contact surface, which are web-like and free in relation to the angled wall element have protruding ends.
- a dry shaver of the type mentioned is known from DE-GM 82 27 546.
- the upper knife of the shaving head consists of a combination of a sieve shear foil part with a comb shear part. Slits forming cutting webs are provided in the comb shear part, which extend into the angled side wall of the comb shear part facing away from the screen shear film, at least two adjacent slits forming a common opening in the angled side wall.
- a cutting web for the bottom knife of the comb shear part is ground in the webs which merge into the angled side wall and the webs ending in front of the angled side wall.
