Abstract
The present invention relates to a device used in an automatic device for preparing paper rolls for web pasting, which is included in a printing system for newsprint and the like. The device automatically attaches one end of a tab, which has been prepared beforehand, to the outer surface of a web's leading end so that the web's leading end, which has been cut into a certain shape (for example, V-shaped), may be fastened to the outer surface of a paper roll on which the web is wound. A tab blank is formed basically by a rectangular support paper, which is provided with adhesive portion's on its upper and lower surfaces, and protective-coating films attached to both surfaces. An upper protective-coating film and the support paper, both of which form a portion of the tab blank, are divided transversely along a dividing line. The tab attaching device embodying the present invention is comprised of a tab loading device for keeping tab blanks in piles. A tab retaining device takes up and retains a retained portion of the topmost of the tab blanks, which are kept in piles in the tab loading device. A tab transporting/pressing device takes up a nonretained portion (or the applied tab) of the tab blank, and thereby removes the protective-coating film, which is held by the tab retaining device, from the nonretained portions lower side, and adhesively presses one end of the nonretained portion, or tab, whose protective-coating film has been removed from its lower side, to the surface of the web's leading end. A protective-coating film discharging device takes up the lower surface protective-coating film and discharges it.
