Title
(EN) A REEL-UP FOR WINDING A PAPER WEB INTO A ROLL AND A METHOD OF WINDING A PAPER WEB TO FORM A ROLL
(FR) ENROULEUSE POUR ENROULER UNE BANDE DE PAPIER ET PROCÉDÉ D'ENROULEMENT DE BANDE DE PAPIER POUR FORMER UN ROULEAU
Abstract
(EN)
The invention relates to a reel-up (2) for receiving and winding into a roll (3) a paper web (W) that arrives from a drying cylinder (17) in a paper making machine (1). The reel-up (2) comprises a rotatably mounted reel spool (4) onto which a paper web (W) can be wound to create a paper roll (3) of increasing diameter and an endless flexible belt (5) mounted for rotation along a predetermined path of travel such that the flexible belt (5) forms a loop. The flexible belt (5) is positioned adjacent to the reel spool (4) to engage the paper web (W) against the reel spool (4) during winding such that the flexible belt (5) is deflected from the predetermined path of travel. According to the invention, the endless flexible belt (5) comprises electrically conductive material such that static electricity in the flexible belt (5) is dissipated away from the flexible belt (5). 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.
(FR)
La présente invention concerne une enrouleuse (2) pour recevoir et enrouler en un rouleau (3) une bande de papier (W) qui arrive d'un cylindre de séchage (17) dans une machine de fabrication de papier (1). L'enrouleuse (2) comprend une bobine d'enroulement (4) montée de manière rotative sur laquelle une bande de papier (W) peut être enroulée de façon à former un rouleau de papier (3) de diamètre croissant et une courroie flexible sans fin (5) montée pour la rotation le long d'un trajet de déplacement prédéterminé de telle sorte que la courroie flexible (5) forme une boucle. La courroie flexible (5) est positionnée de manière adjacente à la bobine d'enroulement (4) de façon à amener la bande de papier (W) en prise contre la bobine d'enroulement (4) pendant l'enroulement de telle sorte que la courroie flexible (5) est déviée du trajet de déplacement prédéterminé. Selon l'invention, la courroie flexible sans fin (5) comprend un matériau électroconducteur de telle sorte que l'électricité statique dans la courroie flexible (5) est dissipée pour s'éloigner de la courroie flexible (5). L'invention concerne également une machine de fabrication de papier dans laquelle l'enrouleuse selon l'invention est utilisée, et un procédé d'enroulement d'une bande de papier.
