Hair cutting apparatus having at least one cutting unit (2) with a stationary cutting member (3) and reciprocable movable cutting member (4) each having cooperating bearing surfaces (7,8) with cutting edges (9,10). To minimize the friction between the bearing surfaces, means (16) with visco-elastic properties are provided between the coupling element (14) and the movable cutting member (4) resulting in a small cutting gap between the bearing surfaces. During cutting of hairs the means with visco-elastic properties behave as a stiff element whereas during periods in which no hairs are cut these means behave relatively soft so that the cutting gaps between the cutting edges are closed. ® KIPO & WIPO 2007 |
