[0002] Self-adhesive stickers are stickers with an adhesive backing. They are typically applied to product packaging to indicate product information, brand logos, or prices. A die-cutting machine for self-adhesive sticker production is used to die-cut printed self-adhesive materials, cutting them into specific shapes and sizes into desired labels, stickers, or films.

[0003] When cutting the base paper used in the production of self-adhesive labels, the cutter may carry paper with it during the rising process. This may be due to the friction or stickiness between the cutter and the paper, which causes the paper to be dragged and cannot be cut normally, affecting the cutting efficiency.
