ABSTRACT:
To deflect a moving paper web to respective transport paths (16, 17, 21, 25) by a cutter cylinder - counter cylinder combination (7, 8), the cylinders are oscillated back and forth above the respective transport paths by being retained in journal bearings which are eccentric with respect to the axes of rotation of the cylinders, so that, as the cylinders rotate, the nip between the cylinders will be in alignment with the respective transport path, the shift directing the leading edge of the web to a respective transport path. The cylinders, each, carry a knife and a counter element diametrically located with respect to each other, so that, as the leading edge of the web is gripped between a respective transport path, the web is severed thereafter and as the cylinder moves into alignment with the other transport path to feed the leading edge of the web to the other transport path for subsequent cutting, and so on.
