Title:

KNIFE FOLDING DEVICE

Document Type and Number:

WIPO Patent Application WO/2011/086700

Kind Code:

A1

Abstract:

A knife blade (5) and a pair of folding rollers (6a, 6b) are disposed at a folding position so as to face each other across a support surface (4) for supporting the lower surface of a paper sheet (S). The knife blade is caused by a knife drive unit (7) to reciprocate between a first position which is spaced upward from the support surface and a second position which is close to the gap between the pair of folding rollers. Each time when the paper sheet (S) is set at the folding position, the knife blade reciprocates once to perform folding operation. The paper sheet (S) is conveyed to the folding position by a conveyor belt (13). The conveyor belt (13) is driven by a first servomotor (11). A control unit (12) controls the rotation of the first servomotor (11) and, before the paper sheet (S) makes contact with a stopper (14), reduces the speed of the servomotor (11) at a predetermined deceleration to prevent the paper sheet (S) from bouncing from the stopper (14).
