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 (). 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. According to the invention, the endless flexible belt () comprises electrically conductive material such that static electricity in the flexible belt () is dissipated away from the flexible belt (). The invention also relates to a paper making machine in which the inventive reel-up is used and to a method of winding a paper web.
