HAIR-TRIMMING APPARATUS

摘要

"Hair-trimming apparatus." A hair-trimming apparatus suitable for thinning hair comprises comb-like stationary and drivable cutting elements which cooperate with one another in such a manner that in all positions of the drivable element a space exists between every two adjacent pairs of cooperating teeth (6 and 7) of the two cutting elements so that the teeth can penetrate the user's hair. The cutting edges of the teeth of at least one of the cutting elements are formed by re-entrant portions (21) of the side edges of the teeth so that only some of the hairs which enter the spaces between adjacent pairs of cooperating teeth are cut. The drivable cutting element preferably reciprocates in a direction parallel to that in which the teeth project from the cutting elements, but it can have other modes of movement, for example, rotary.
