CA 2260074

A winding machine is proposed for continuous winding of a material web, in particular a paper or cardboard web, onto a reel into a winding roll, having a movable pressing drum, which forms a winding gap with the winding roll, having at least one primary transport device by means of which the reel can be moved along a first guide track, and at least one secondary transport device that guides the reel along a second guide track. The winding machine is distinguished in that in order to prepare for a reel change, the new reel (35; 49) can be shifted by means of the primary transport device (79) into a reel-changing position in which a new winding gap is formed between the new reel (35; 49) and the pressing drum (19), and that in the reel-changing position, the material web (3) is guided over a circumference region of the new reel (35; 49).

L'invention concerne une bobineuse permettant de bobiner en continu une bande de matériau, notamment une bande de papier ou de carton, sur un tambour, afin de former un rouleau enroulé. Cette bobineuse comprend un tambour de serrage déplaçable qui forme une fente d'enroulement conjointement avec le rouleau enroulé, au moins un dispositif de transport primaire grâce auquel le tambour peut être déplacé le long d'une première glissière de guidage, et au moins un dispositif de transport secondaire qui guide le tambour le long d'une seconde glissière de guidage. Cette bobineuse se caractérise en ce que pour préparer un changement de tambour, le nouveau tambour (35; 49) peut être déplacé dans une position de changement de tambour à l'aide du dispositif de transport primaire (79), position dans laquelle une nouvelle fente d'enroulement est formée entre le nouveau tambour (35; 49) et le tambour de serrage (19). En position de changement de tambour, la bande de matériau (3) est guidée sur une zone périphérique du nouveau tambour (35; 49).
