Abstract

PURPOSE:To obtain the high-speed operation of a rotary press and improve the accuracy of chopper folding by using a cam mechanism and a lever connecting mechanism for giving vertical movement to a chopper blade. CONSTITUTION:For adapting for a high-speed operation, a free-shaped cam 17 is provided to be rotated in contact with a cam roller 16 at the end of a lever 12 so that the stroke of the vertical movement of a chopper blade 3 may be reduced and the speed to push in folded papers 1 and 2 into a folding roller 6 may be freely set. Since the roller 16 is lightly pushed to the cam 17 by the work of a spring 14, it is rotated in accordance with the rotation of the cam 17, and the lever 12 is oscillated round the axis of a hinge 5 as an arrow B shows. By this oscillation, the shaft of the hinge 5 is rotated as an arrow C shows, and accordingly the blade 3 is vertically moved. In this construction, the vertical stroke C' of the blade 3 between the finish of a push-in and the beginning of the next push-in is reduced and the total stroke A' can be greatly reduced. Since the blade 3 is stopped in the greater part of the duration of the stroke C', vibration is reduced, and improvement is given to the accuracy of chopper folding of the blade 3.
