Abstract
In an improved process for processing a film web, the film web is cut in the longitudinal direction, forming a marginal strip and a remaining film web with a width reduced by the width of the marginal strip. The marginal strip is transferred to a movable film-drafting device on which is arranged a gripper. The remaining film web is separated entirely or partially by cutting and also possibly by tearing. The film-drafting device is moved along one side of a roller arrangement, threading the film web into the roller arrangement. The film-drafting device is moved along one side of a winding device comprising at least one winding roller up to a release or end position. The film-drafting device is opened at the end position to release the marginal strip.
