Abstract

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.
