Reel-up and a method for winding into a roll a paper web and for starting a new roll

Abstract

The invention relates to a reel-up () for receiving and winding into a roll () a paper web (W) that arrives from a drying cylinder in a paper making machine and for starting a new roll () from a tail () formed by cutting the paper web (W). The reel-up () comprises a rotatably mounted reel spool () onto which a paper web (W) can be wound to create a paper roll () of increasing diameter; and an endless flexible belt () mounted for rotation along a predetermined path of travel such that the flexible belt () forms a loop. The flexible belt () is positioned adjacent to the reel spool () to engage the paper web (W) against the reel spool () during winding such that the flexible belt () is deflected from the predetermined path of travel by an amount relative to the amount of paper material wound on the reel spool (). A pair of water nozzles () is arranged such that each water nozzle () can direct a web-cutting water jet stream against the paper web (W) to cut the paper web (W) at a point before the paper web (W) reaches the flexible belt (). Each water nozzle () is arranged to be movable in a direction which is transverse to the direction of movement of the paper web (W) and a glue nozzle () is arranged to direct a stream of glue against the reel spool () or against the tail (). The invention also relates to a corresponding method for operating the reel-up.
