- a guide roller pair for bringing the laminated product close to the fixed blade is provided in the proximity of the front and rear of the movable blade so that there is no gap between the laminated product and the fixed blade. (Not shown).
- the guide roller pair is rotated so as to assist the conveyance of the laminated product in the traveling direction, and the rotation speed is set so as to substantially match the conveyance speed of the laminated product.
- the R shape of the fixed blade 71 and the movable blade 72 for performing the R-cut is set to a slightly larger R diameter than the designed R diameter, and the first and second rear ends of the laminated product due to mechanical variation. The end portion of the R portion is not traced with respect to the variation in the distance from the front end.
- the movable blade 72 or the R cut unit 70 including them and the side slitter 60 are structured so as to be detachable from the cut unit 50, only the failed side immediately when one of the cutters fails Therefore, maintenance and inspection can be facilitated and serviceability can be improved.
- the laminated product after cutting is sent from the discharge rollers 80 and 81 to the output tray 4 to complete the laminating process, and the laminated product in the output tray 4 has an optimum width in the vertical and horizontal margins of the film. Since the four corners are cut in a round shape, it is safe and can be used immediately for various applications.
