ABSTRACT:
A lower guillotine cutter blade (2) is mounted to a frame (1). A guillotine cutter-blade holder (3) holds an upper guillotine cutter blade (4) and vertically reciprocates with respect to the lower guillotine cutter blade (2). Rods (6) are vertically slidably mounted to the guillotine cutter-blade holder (3). A pressing plate (5) is secured to the lower ends of the rods (6). Springs (7) are fitted around the rods (6) between the guillotine cutter-blade holder (3) and the pressing plate (5) for downwardly elastically biasing the rods (6) so that the heads (6a) of the rods are kept abutted against the guillotine cutter-blade holder (3). In a cutting operation, after the pressing plate (5) is brought into abutment with a batch of paper (20), the guillotine cutter-blade holder (3) is further downwardly moved, thereby causing the lower and upper guillotine cutter blades (2and4) to cut the batch of paper (20) and also causing the heads (6a) to upwardly protrude from the guillotine cutter-blade holder (3). At this time, a sensor (8) mounted to the guillotine cutter-blade holder (3) detects the distance to the heads (6a). A thickness measuring element (27) determines the thickness of the batch of paper (2) on the basis of the detection signal.
