    • A rotary cutter comprises a first knife located on a knife shaft having a longitudinal axis, a second knife spaced from the first knife by an adjustable cutting gap, a control unit including a drive for turning at least one of the first knife or the second knife, and an adjusting mechanism for moving at least one of the first knife or the second knife in the direction of the longitudinal axis to adjust the cutting gap. The adjusting mechanism comprises a first signal transmitter for detecting a zero position of the first and second knives; a second signal transmitter for detecting the cutting position of the first and second knives; and an adjustment drive coupled to the first and second signal transmitters for movement of at least one of the first or second knives from the zero position to the cutting position.
    • 旋转切割机包括位于具有纵向轴线的刀轴上的第一刀,通过可调节的切割间隙与第一刀间隔开的第二刀,包括用于转动第一刀或第二刀中的至少一个的驱动器的控制单元 以及用于沿纵轴方向移动第一刀或第二刀中的至少一个的调节机构,以调整切割间隙。 调节机构包括用于检测第一和第二刀的零位置的第一信号发射器; 第二信号发射器,用于检测第一和第二刀的切割位置; 以及耦合到第一和第二信号发射器的调节驱动器,用于使第一或第二刀中的至少一个从零位置移动到切割位置。
