    • As shaving system comprises a shaving head structure; a blade frame defining a longitudinal axis; and at least two blades mounted in the blade frame, each having a cutting edge extending parallel to the longitudinal axis. The frame is mounted on said structure for oscillatory motion perpendicular to, or about an axis parallel to, said longitudinal axis; and a drive system coupled to said frame produces said oscillatory motion. The amplitude of said oscillatory motion is chosen to exceed 0.4 mm and the frequency exceeds 80 Hz go give an average cutting speed greater than 400 mm per second. In one embodiment at least one blade faces in each of two opposed shaving directions, and the amplitude of said oscillatory motion exceeds the spacing between the cutting edges of said oppositely facing blades. The spacing is preferably in the range 0.6 to 1.4 mm and said amplitude is preferably in the range 0.4 to 2.0 mm.
    • 由于剃须系统包括剃须头结构, 限定纵向轴线的刀架; 以及至少两个安装在叶片框架中的叶片,每个叶片具有平行于纵向轴线延伸的切割边缘。 框架安装在所述结构上,用于垂直于或平行于所述纵向轴线的轴线进行摆动运动; 并且连接到所述框架的驱动系统产生所述振荡运动。 所述振荡运动的幅度被选择为超过0.4mm,并且频率超过80Hz,则平均切割速度大于每秒400mm。 在一个实施例中,至少一个刀片面向两个相对剃须方向中的每一个,并且所述摆动运动的幅度超过所述相对面向的刀片的切割边缘之间的间隔。 间距优选在0.6至1.4mm的范围内,并且所述幅度优选在0.4至2.0mm的范围内。
