CUTTING DEVICE AND METHOD FOR WIDE STRIP PHOTOSENSITIVE MATERIAL AND CONTROL METHOD OF CIRCUMFERENTIAL SPEED RATIO OF UPPER EDGE TO LOWER EDGE

摘要

PROBLEM TO BE SOLVED: To provide a cutting device and method suppressing the peeling of a photosensitive layer on a cutting surface in the whole range from a low feed speed range to a high feed speed range, when the wide-width strip photosensitive material is cut into narrow-width ones by a shear cutting method.;SOLUTION: This cutting device is provided with multiple sets of rotating edges comprising sets of upper edges and lower edges rotating in the mutually inverse direction and cuts the running wide-width strip photosensitive material into multiple narrow-width belt-shaped photosensitive materials along the running direction. This cutting device for the wide-width strip photosensitive material is characterized in cutting the photosensitive material by changing the circumferential speed ratio of the rotating edges according to the feed speed of the wide- width strip photosensitive material.;COPYRIGHT: (C)2003,JPO
