Finishing method and finishing tool for base paper of printing paper

Abstract

The invention relates to a finishing method and a finishing tool for base paper of printing paper. The base paper of the printing paper comprises edge parts on the two sides, the edge parts comprise atearing part, and the finishing method for the base paper aims to cut the tearing part into a notch with an arc-shaped structure; the finishing tool for the base paper of the printing paper comprisesa mold and a scraper, the mold includes a flat panel and an arc panel, and the surface of the arc panel and the surface of the panel are vertically fixed together; the connection between the arc panel and the flat panel is intersecting lines, a gap is located in the middle of the connection between the arc panel and the flat panel, the gap has intersections of the two ends, and the intersectionsare on the intersecting lines; and the edge of the arc panel for forming the gap is a first arc, and the edge of the flat panel for forming the gap is a second arc, and the formed gap has a structurewith a middle width. The finishing method for the base paper of the printing paper and the finishing tool have the advantages that the base paper of the printing paper does not break during printing and the production does not delay after the base paper of the printing paper with a fracture phenomenon is finished.

Description

technical field [0001] The invention relates to a finishing method and a finishing tool for base paper of printing paper. Background technique [0002] Printing paper base paper is a structural base paper rolled into a cylindrical shape. After the printing paper base paper is unrolled, it becomes a long strip of paper. The printing paper base paper is printed on a printing machine. [0003] There are multiple winding rollers on the printing machine. During production, it is required that there is no tearing on the side of the printing paper base paper. Otherwise, the printing paper base paper will be wound and pulled by the winding rollers on the printing machine. Due to the pulling force, the printing paper base paper will be easily from The extension part is torn and broken, which leads to the suspension of production. Reconnecting the broken printing paper base paper and continuing production requires more processes and delays production. Therefore, it is necessary to fin...
