    • 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 a visco-elastic element is 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 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.
    • 具有至少一个具有固定切割构件(3)的切割单元(2)和往复运动的可移动切割构件(4)的切割装置,每个切割单元具有与切割边缘(9,10)配合的支承表面(7,8)。 为了最小化轴承表面之间的摩擦,在联接元件(14)和可移动切割构件(4)之间提供了一个粘弹元件,从而在支承表面之间产生小的切割间隙。 在切割头发期间,粘弹性元件表现为刚性元件,而在没有毛发切割的时期,元件的行为相对较软,使得切割边缘之间的切割间隙被封闭。
