ABSTRACT:
A paper roll stand holds a paper roll in such a manner as to allow it to rotate in two opposite directions so as to temporarily locate a leading web end on a table board. An arm assembly positioned above the table board is movable in the lengthwise and lateral directions. The arm assembly includes a suction cup device for lifting up the outermost web of the paper roll, a cutter device for cutting the paper web, and a tape-attaching device for adhesively attaching web pasting adhesive tapes to the web's leading end. A device for adhesively attaching a head of a web end-fastening strip to an inner side of the web's leading end is located below the web. A paper roll-pressing device for adhesively fastening a tail of the web end-fastening strip to the outer surface of the roll is also included. A new paper roll prepared for web pasting according to the present invention is brought to the paper roll stand of a printing unit and rotatably held thereon. This new, prepared, roll is rotated at a set rate on the reel stand, and, by pressing the end of an old, expiring, web against the leading web end of the new roll, the expiring web is adhesively pasted to the new web leading end.
