Abstract

A method is provided for switching reels in a paper machine that includes applying an adhesive onto a continuously running paper web to begin a new paper roll and severing the continuous paper web from the tail end of the newly completed roll. The running paper web is supported by a reel drum and wound onto exchangeable reel shafts in contact with the reel drum in order to form rolls of paper. A hopper with a heater heats an adhesive agent to temporarily lower its viscosity and stickiness for smooth and even applying. A pair of nozzles, mounted on a pair of rodless cylinders and translating therewith, spray jets containing said adhesive onto the web and/or the reel shaft. The web is then advanced onto the reel shaft thereby forming an adhesive interface between the web and the shaft. Tension is applied across the adhesive interface to sever the paper web at the adhesive interface, thereby separating the trailing end of the paper web of the previously completed roll from the current paper roll.
