Title:
PAPER CUTTING DEVICE IN FOLDING DEVICE FOR FORM PRINTING MACHINE
Document Type and Number:
Japanese Patent JPH0976460
Kind Code:
A
Abstract:

To simplify a processing after folding operation by a device wherein a cut line having a joint line left therein is made by a cutting cylinder on a continuous paper at every predetermined number of folding sheets and a nozzle roller is pressed to a receiving roller when the cut line gets to just before the upstream side of the nozzle roller of an oscillating shooter so as to cut off.

When a mark which is marked on a continuous paper 1 is detected, a cutting cylinder 19 acts eccentrically in a direction to approach an impression cylinder 18 so as to make a cut line by leaving a joint line at a lateral perforation. The cut line section passes a guide roller 39b in that state and enters an oscillating shooter 3. When the cut line section gets to just before a nozzle roller 5, the nozzle roller 5 is pressed to a receiving roller 4. Thus, the downstream side of the cut line section of the continuous paper 1 is pulled by the nozzle roller 5 which is rotating faster than the travelling speed of the continuous paper 1, so that the joint line of the cut line section is torn and the continuous paper 1 is cut off from the cut line section. After the operation, the nozzle roller 5 is operated in a direction to release the pressing to the receiving roller 4.
