(FR) TÊTE DE RASAGE AMÉLIORÉE AVEC COMMANDE BOMBÉE
Abstract
(EN)
A cutter unit (1) for a rotary shaver is formed by an outer cutting element or cap (2) which interacts with a rotating inner cutting element or cutter (4) to trap and cut hairs. The cap has an annular shaving track (8) of domed cross-section having slots (30) through which the hairs may protrude. The cutter has a convex upper face (22) to engage the shaving track and a concave forward face (26).

La coiffe comporte une piste de rasage annulaire (8) à profil bombé comportant des fentes (30) par lesquelles les poils peuvent dépasser. La lame présente une face supérieure convexe (22) coopérant avec la piste de rasage et une face avant concave (26).
