Abstract
A web passes over a drive roller onto a reel which becomes fully wound; the full reel is moved away from the drive roller; an empty reel engages the drive roller; a web shifting element lifts the web, in a direction counter to the rotation direction of the drive roller, to form a loop that wraps around the empty reel; a transport element may upraise the web at the other side of the drive roller so that the web loop may enter either the nip defined between the web and the empty reel with the web upraised or the nip between the empty reel and the drive roller with the transport element down; the web shifting element and/or the transport element may include an air cushioning device for the web.
