The blade is conveyed in the direction of the proximity sensor, and the blade approaches the film and cuts the film. When the blade approaches the fourth proximity sensor, the fourth proximity sensor sends a signal to the controller, and the controller stops the second motor 37, so that the third conveyor belt 34 stops conveying the blade. At this time, the blade completes the film cutting work and is in the initial position. At the same time, the controller turns on the first motor 72, and the first motor 72 drives the first conveyor belt 121 and the second conveyor belt 221 to convey in the direction close to the lower pressure plate 42. When the cross plate 81 approaches the first contact sensor, the first contact sensor sends a signal to the controller, and the controller stops the first motor 72.
