A winding apparatus for transferring a web from a carrier drum to a spool. Pressure between the spool and the carrier drum is higher in the area of the feed strip of the web by applying a higher contact force, or by orienting the spool and drum at an angle to one another.

Method for transferring a feed strip of a material web onto a winding device

Process and apparatus for winding a running material web, in particular a paper or cardboard web, in which the running material web is wound consecutively on several winding cores, in particular reel spools. At least one cut is made preferably running parallel to the web edge of the running material web and in the web travel direction of the running material web. After the started at least one cut has run through the nip formed by the winding roll and the new winding core, the at least one formed transfer strip which is incorporated in the running material web is detached from the outer circumferential area of the winding roll by at least one directed high-energy air jet that is generated briefly by at least one separator device and simultaneously cuts through. Subsequently, the at least one now detached transfer strip is transferred onto, and preferably applied to, the outer circumferential area of the new winding core by at least one first blower device, in particular a blower shoe.

Process for winding a running material web and winding apparatus for conducting the process

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.
