ABSTRACT:
This cutting apparatus includes a frame structure supporting a cutting roller and a counter pressure roller arranged at an angle relative to the feed advance direction of sheet material to be cut. Drive means are provided for the cutting roller and for the counter pressure roller in the form of a common drive chain positively interconnecting the rollers with a drive motor through an instantaneously operable clutch, such as an electro-magnetic or pneumatic clutch. A brake is provided between the cutting roller and the frame structure, whereby the control of the clutch and of the brake is such that engagement of the positive drive through the clutch disengages the brake and vice-versa.
