Abstract
The disclosure concerns both an apparatus and a method for replacing a finished web roll with an empty core and roll support in a double-drum type web winder. The web winder has a winding station at which a pair of drums wind a web on a roll support carried on an extractable core. The finished roll is moved across a transfer table to an extraction table at which the core is removed laterally. At the extraction station, the removed core is reinserted in a new web roll support. The core and new web roll support are pivoted up to an upraised waiting position. A newly finished roll at the winding station is moved toward the extraction station. The new web support and the core within it are moved above the just-finished roll and are delivered to the winding station for winding the next web roll on the core and new roll support.
