Abstract
Hair cutting apparatus having at least one cutting unit () with a stationary cutting member () and reciprocable movable cutting member () each having cooperating bearing surfaces () with cutting edges (). To minimize the friction between the bearing surfaces a visco-elastic element is provided between the coupling element () and the movable cutting member () resulting in a small cutting gap between the bearing surfaces. During cutting of hairs the visco-elastic element behaves as a stiff element whereas during periods in which no hairs are cut the element behaves relatively soft so that the cutting gaps between the cutting edges are closed.
