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.

The invention relates to a method of recovering energy in a forming section of a papermaking or boardmaking machine, wherein stock from a headbox is fed into a forming zone of a forming section, said forming zone including at least one looped forming fabric curving along a convex surface of a support member, and water is drained from the stock through said at least one forming fabric in the forming zone to form a paper or board web, the water passing through said at least one fabric being thrown out from the forming zone and possessing kinetic energy, characterized by placing a movable component in the water thrown out from the forming zone, so as to cause the water to move the component, and thereby recovering part of the kinetic energy. The invention also relates to an arrangement in a papermaking or boardmaking machine.
