• a moving slotter knife base that is movably supported by the fixed slotter knife base in a circumferential direction;
• a second cutting blade that is mounted on an outer peripheral portion of the moving slotter knife base;
• a first drive device that rotationally drives the fixed slotter knife base;
• a second drive device that rotationally drives the moving slotter knife base;
• and
• a control device that drives and controls the first drive device and the second drive device,
• wherein the control device adjusts a relative rotation speed between the fixed slotter knife base and the moving slotter knife base at a start of rotation of the fixed slotter knife base and the moving slotter knife base, so that relative positions of the first cutting blade and the second cutting blade in a circumferential direction are adjusted.
