    摘要: A reel shaft for reeling a paper web in a reel-up, which reel-up includes at least one unit that is mobile in the longitudinal direction of the paper machine and supports a pair of opposite engagement members each of which includes an engagement part, which engagement parts are arranged for rotatably carrying and detachably engaging the reel shaft during reeling. In accordance with the invention, the reel shaft is free of a support shaft and has a self-supporting, tubular sleeve substantially formed of fiber-reinforced plastic, which sleeve has an envelope surface on which the initial wrapping of the paper web shall be performed, and also an internal surface defining an axial channel terminating in axial openings at the ends of the reel shaft. The invention also relates to a reel-up for such reel shafts.

    摘要: A dry end of a tissue machine is made shorter by close-coupling a reel-up to the drying section and supporting the web from the drying section to the reel-up by a foil or a belt such that web stability is maintained, thus allowing high-speed operation. The foil's downstream edge can form a nip with the paper roll and nip load can be controlled by controlling pivotal movement of the foil. The reel-up can include a calendering belt for calendering the web as it passes through a nip between the belt and a reel drum supported on the belt, and a rotatable reel spool on which a paper roll is wound in nipping engagement with the reel drum. Alternatively, the reel drum can be eliminated and the paper roll can be supported on the belt. A composite shaftless core for winding is also disclosed.
