Abstract

This tab surface-protective paper separating device is what removes from a tab stuck on the leading web end of a paper roll the protective paper which is attached to the outer surface of the tab except on portions along its edges; it is comprised of a table board upon which a leading web end with a tab stuck thereon is brought, a scraper which is designed to be moved transversely along the table top and is capable of being wedged into inadhesive peripheral points between the base tab and its protective paper, and a gripping claw for holding the protective paper between the scraper and itself in coordination with the wedging movement of the scraper. In seizing the protective paper between the scraper and the gripping claw, the device wedges the scraper between the tab and its protective paper with the help of ejection of compressed air. The protective paper is automatically removed from the tab as the scraper and the claw, both holding the protective paper therebetween, are moved away from the table board.
