CA 2441196

A multi-reel apparatus for use in a drying section of a papermaking machine allows a web to be continuously wound without interruption. The apparatus includes a web support and a pair of vertically stacked reeling stations located along an inclined portion of the web support. Each reeling station has at least one reeling device operable to hold and rotatably drive a core onto which the web can wound to form a roll. Each reeling device is further operable to move the core into engagement with the web on the web support to initiate winding of the web onto the core, and to move the core away from the web support when the roll is fully wound. Winding is alternated between reeling devices, allowing the completed roll to be removed and a new core to be loaded at one reeling station while the other reeling station continues in full winding operation.

L'invention concerne un appareil à bobines multiples conçu pour une section de séchage d'une machine de fabrication de papier, ledit appareil permettant d'enrouler une bande en continu et sans interruption. Cet appareil comprend un support de bande et une paire de postes de bobinage empilés verticalement situés le long d'une portion inclinée du support de bande. Chaque poste de bobinage comprend au moins un dispositif de bobinage fonctionnant pour tenir et entraîner de manière rotative un cône, sur lequel la bande peut être enroulée pour former un rouleau. On peut faire fonctionner chaque dispositif de bobinage pour déplacer le cône et le mettre en contact avec la bande sur le support de bande, de manière à commencer l'enroulement de la bande sur le cône, et à éloigner le cône du support de bande, lorsque le rouleau est complètement enroulé. L'enroulement s'effectue de manière alternée entre des dispositifs de bobinage, ce qui permet de retirer le rouleau complet et de charger un nouveau cône au niveau d'un poste de bobinage, tandis que l'autre poste de bobinage continue son processus d'enroulement complet de bande.
