ABSTRACT:
In a winding machine for the production of at least one coil (10) of a supplied material web, such as in particular a paper web and/or a card web, the material web (12) is guided through a longitudinal cutting device (16) and the partial webs of the longitudinally cut material web (12) are each wound up onto a core (18), in particular a core (18) formed by a sleeve. A coil (10) arising on the core (18) is supported by at least one support roll (20), in particular a drivable support roll, and the hardness of the winding can be influenced by a web tension interruption device (22). The web tension interruption device (22) is provided in the running direction of the web directly in front of a position (S) where the supplied material web (12) or its partial webs run onto an associated support roll (20), and is also arranged between the longitudinal cutting device (16) and the run-on position (S). It includes at least one roll (24) spatially separate from the associated support roll (20). The at least one roll spatially separate from the relevant support roll (20) can be driven. The web tension interruption device (22) is subdivided transversely to the web running direction (L), and at least one segment is associated with each partial web of a longitudinally cut material web (12). The tensions of the various partial webs can be controlled independently from one another via the segments or segment groups associated therewith.
