<p>The machine (1) has rotary upper and lower cutters (4, 5) through which a shingled stream (12) of print products is guided by a conveying device e.g. belt. One of the cutters has cutting edges, which are arranged in a circumference in a distributed manner. A control device (S) controls driving of the cutters. The control device determines or control rotational speed of the cutters based on a conveying speed of the conveying device and a thickness of the shingled stream. The cutters are driven by motors (M, M').</p> |
