A method and device for winding a paper web to form a reel. The web is wound onto a shell that is predominantly centrally driven to introduce a torque that winds the web on the shell into a reel. A pressure element extends over the width of the web and acts continuously on the outer surface of the reel being wound in order to squeeze out air. A web threading roll comes adjacent the shell during web threading. Once the web is threaded, the shell is moved generally horizontally from the web threading toward the main winding position where the web is wound. A compensation device supports the reel being wound. The first pressure element in contact with the reel may move away, and a second pressure element closer to the compensation device may press upon the reel, after the first pressure element has moved away.

Méthode et dispositif permettant d'enrouler une bande continue de papier de manière à former une bobine. La bande est enroulée autour d'un cylindre, qui tourne sur son axe de manière à créer un couple, de sorte que la bande s'enroule sur le cylindre et forme une bobine. Un élément presseur se prolongeant sur toute la largeur de la bande agit en continu sur la surface externe de la bobine en formation afin d'en expulser l'air. Un rouleau d'amorçage vient se placer à côté du cylindre pendant l'amorçage de la bande. Une fois la bande amorcée, le cylindre se déplace essentiellement horizontalement, de la position d'amorçage vers la position d'enroulement principale où la bande est enroulée. Un dispositif compensateur supporte le cylindre pendant l'enroulement de la bande. Le premier élément presseur peut être retiré et un second élément presseur, situé plus près du dispositif compensateur peut s'appuyer contre le cylindre, une fois le premier élément presseur enlevé.
