Abstract
Device and process for winding a material web onto a winding core to form a wound reel. The device includes a reeling drum positionable against a winding core or a wound roll to form a winding nip, a secondary transport device to displace the winding core/wound roll along a path of travel, and a pressure device and an air squeezing element. Secondary transport device carries air squeezing element and pressure device, and pressure device is arranged to press air squeezing element against wound reel prior to a reel change. A primary transport device moves a new, still-empty reel spool into an initial winding position, and a lift device is coupled to air squeezing element and pressure device and to secondary transport device. Lift device is arranged to move air squeezing element and pressure device to distance from a rotational axis of wound reel which corresponds to a current layer thickness. The process includes guiding the material web over the reeling drum, and forming a winding nip between reeling drum/wound reel, moving the squeezing device and the pressure device toward wound reel to a distance which corresponds to a current layer thickness, pressing squeezing device against wound reel, and moving wound reel, squeezing device, and pressure device away from reeling drum and along a path of travel to a reel spool changing position.
