ROTARY TYPE PUNCHING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a rotary type punching machine capable of performing a high-mix low-volume production at a low cost.SOLUTION: A single sheet S is either advanced intermittently, or advanced or retracted repeatedly in synchronism with the rotation of a pair of a magnet roller 16 and a reception roller 17 by a transportation roller pair 23a and 23b. While the sheet is passing through the pair of the magnet roller and the reception roller, the pair of the magnet roller and the reception roller is rotated a plurality of times to perform punching processing of the sheet.
