Sheet material slitting device

摘要

Sheet material slitting device, in the case of which there are provided, situated alongside one another, a first slitting device shaft (18) and a second slitting device shaft (20) which rotate in opposite directions synchronously with the speed at which sheet-like or web-like material (12) is advanced; a first slitting knife (14) which is arranged with respect to a ring (22) which is fastened to the first slitting device shaft (18); and a pair of second slitting knives (16) which are arranged with respect to a ring (24) fastened to the second slitting device shaft (20) and having a predetermined distance between them in the axial direction, the said components being constructed in such a way that slitting of the sheet-like material (12) is carried out by interaction of the first slitting knife (14) with the second slitting knives (16), characterised in that the slitting device has an eccentric part (38) which is adapted to the first slitting device shaft (18) and the axis of which is offset in relation to the axis of the first shaft (18); a holding ring (42) which is rotatably mounted, with a degree of play, around the outside circumference of the eccentric part (38) and on which holding ring (42) the first slitting knife (14) is fastened in such a way that it is possible for an edge (14a) of the slitting knife (14) to extend outwards radially from the circumferential surface of the ring (22); and a rotating device (40) to make it possible for the holding ring (42) to rotate with respect to the eccentric part (38), and in that the ...
