Abstract
In a winding machine, the space defined by the support cylinders and the winding rolls is sealed and an overpressure is created in this space to relieve the force with which the winding rolls press against the support cylinders. For the purpose, in the area of the two lateral ends of the support cylinders sealing elements are arranged, which for adjustment to various web widths, are axially displaceable and at the same time can be moved away to an area outside the motion range of guide heads and their mounting. In the sealing position of the sealing elements, a fictional-look connection with the support cylinders is avoided.
