Automatic device for preparing paper rolls for web pasting

Abstract

The present invention relates generally to equipment for a printing system for newsprint and the like and, more particularly, to a device for automatically preparing leading web ends of paper rolls for automatic web pasting. A device embodying the present invention is supported generally from a ceiling of a room and extends downwardly when used. The device comprises a structural support which is both vertically extensible and collapsible, an arm extended sideways and capable of movement in directions both parallel to and perpendicular to the axis of a paper roll, a suction cup device for lifting the outermost web of the paper roll, a cutter device for cutting the paper web of the paper roll, a 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, and a paper roll-pressing device for adhesively fastening a tail of the web end-fastening strip to the outer surface of the web. A paper roll prepared for web pasting according to the present invention is rotated at a set rate on a reel stand. By pressing the expiring web being fed into a printing machine against the leading web end thus prepared with adhesive of the rotating paper roll, the expiring web is adhesively pasted to the leading web end of the new paper roll. This method of adhesive-based web pasting enables the printing machine to be fed with paper continuously.
