作業性が悪い現状にある。Prior Art Currently, paper rolls often get scratched or dirty during transportation, and workers cut out the defective parts using a scalpel or cutter, adjusting the force depending on the depth of the scratches or stains. For this reason, it is often difficult to accurately remove only the defective parts, such as cutting too much of the paper web, or not cutting enough.Also, since the cuts are linear, it is difficult to remove only the defective parts. It takes a lot of work to spread it out and peel it off, and the workability is currently extremely poor.

い。 That is, the inclined guide surface 5, which has a width W narrower than that of the guide plate 4, gently rises from the middle of the guide plate 4. Grip part 7 having a guide lower surface 6 with a width
are integrally attached with a gap S between them, and this gripping part 7 has a hollow part 1 located above the inclined guide surface 5.
1 are provided, and cutter blades 8,
Slits 12, 12' are provided so that the tips of the cutter blades 8' reach therein, and cutter blades 8, 8' are inserted into these and fixed with screws 13, 13'. Cavity part 11
The height of the guide plate 4 and the gap S between the guide plate 4 and the lower guide surface 6 of the gripping part 7 are naturally larger than the thickness of the wrapping paper to be cut. Note that the width of the guide plate 4 may not be made wider than the inclined guide surface 5, but may be made to have the same width.

去された巻取紙が得られることになる。 As explained above, insert the tip of the guide plate 4 of the roll paper defect removal cutter 1 into the part deeper than the scratch 2 made on the roll paper 3, hold the grip part 7, and move it as shown in FIG. When you do this, information board 4
The laminated paper guided upward is lifted upward by the inclined guide surface 5 having a gentle slope and is pressed against the cutter blades 8 and 8' which are inclined forward, and is also pushed against the lower guide surface 6 of the gripping part 7. As the laminated paper is pressed, as shown in FIG.
14' remains as it is guided by the groove formed by the guide plate 4, the lower guide surface 6, and the side wall 9. Therefore, when the ends 14, 14' of the laminated paper are grasped and spread out as shown in FIG. 4, a web with scratches 2 removed will be obtained.
