Description
されてもよい。距離「d2」は、前壁34に最も近い第1の刃先26aにおいて最大であってよく、後壁35に最も近い位置において最小であってよい。理論に束縛されるものではないが、前壁34に近いほど距離「d2」を増加させることにより、切断効率が改善すると考えられる。毛が第1の刃先26aによってトリミングされた後、毛はより短くなっているので、平らに寝た状態にはよりなりにくくなる。したがって距離「d2」は、第2の刃先26bの位置ではより小さくなっていてよく、後壁35に最も近い刃先26cの位置では、距離「d2」は更に小さくなっていてよい。特定の実施形態では、距離「d2」は、刃先26a、26b、及び26cのいずれかの位置で測定して、約0.5~約3mmであってよい。
