Abstract (en)
A slotting device for a linear succession of moving sheets, being part of a creasing and slotting machine, with arcuate knives (10, 11) being mounted separately on a pair of rotating knife gears (9, 8) each driven independently about a common axis by a pair of gears (15, 14) rotatably mounted on a pair of driveshafts (17, 16) driven by computer-controlled motors. The knives may be accelerated and decelerated independently to assume instantaneous positions relative to each other and to a sheet to be cut, in order to determine the length and spacing of successive cuts. The knives may be mounted on a common axis as illustrated or on separate axes spaced apart along the line of travel of the sheets. <IMAGE>
