Abstract (en)
[origin: JPS6445594A] PURPOSE: To quickly separate joint-less paper webs folded in zigzag by arranging a flat cutting member provided with a cutting blade on a horizontal surface between a turning position in a first carrying block and a contact surface in a second carrying block so that it crossess the second carrying block freely to move forward and backward. CONSTITUTION: Paper webs to be carried are dropped on a middle or a high contact surface 11 of a plate 10 through a turning roller 4, and collected between a pair of vertical guide surfaces 8, 9. The plate 10 is dropped in order so that a lamination 6 is formed on the plate 10 at a desirable height between guide means 7, 7'. In this condition, compressed air is supplied to a cylindrical piston unit 19, and a cutter 15 is moved forward so as to cut the following paper web along the folding line of the lamination 6. Thereafter, the plate 10 is dropped to a carrying block 16, and the lamination 6 is placed on the carrying block 16 for discharge. The plate 10 is reset to a position at the end of the upper side, and the cutter 15 is moved backward, and a new lamination on the cutter 15 is placed on the plate 10.
