Method for winding a tissue web in a reel-up in a paper machine
First Claim
1. A method for winding a traveling web of fibrous material, comprising the steps of:
- guiding the web toward a rotating reel shaft;
applying an adhesive onto at least one of the web and the reel shaft;
initiating contact between the web and the reel shaft such that the web adheres to the reel shaft forming an adhesive interface therebetween, a trailing end of the web extending from the adhesive interface in a downstream direction, and a leading end of the web extending from the adhesive interface in an upstream direction; and
severing the web at the adhesive interface by applying tension to the trailing end of the web in the downstream direction, the adhesive preventing the web from detaching from the reel shaft such that the trailing end of the web tears free of the leading end at the adhesive interface.

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.
