Abstract
A slit line making mechanism includes a first roller, a second roller, a feeder motor, a slit cutter, and a slit cutter motor. The feeder motor is controlled to rotate the second roller and then the first roller after insertion of a lead end of a film roll/bags-on-a-roll through the gap between the first roller and the second roller and the gap between the second roller and the slit cutter, thereby delivering the film roll/bags-on-a-roll to a reel replacement unit for dispensing. The feeder motor is controlled to rotate the second roller in delivering the film roll/bags-on-a-roll, and the slit cutter motor is controlled to rotate the slit cutter each time the second roller is rotated to deliver the film roll/bags-on-a-roll to a predetermined distance, causing the slit cutter to make a slit line on the film roll/bags-on-a-roll.
