ABSTRACT:
A winding device for paper or cardboard with at least two axis-parallel support elements for the sheet winding, which extend at least over the length of the sheet winding (T) and of which at least one is a carrier roll (2). The other support element has a rigid carrier (4), which guides the sheet winding over a sheath (7, 7') arranged in a rotating manner around the carrier or guided in a flexible tubing manner, and a carrying shoe (5, 5') combined with it and acting hydrodynamically with respect to sheath (7, 7'), which carrying shoe is provided with a concave pressure surface whose radius of curvature essentially corresponds to the maximum winding (T) including the sheath wall thickness, whereby carrying shoe (5, 5') can be adapted in its position to the size (position of the periphery) of the sheet winding (W') which is wound and present each time.
