WINDING DEVICE FOR SHEETS OF PAPER OR CARDBOARD

摘要

A winding device for sheet material such as paper, cardboard and the like includes at least two axis-parallel support elements for the sheet material being wound, which extend at least over the length of the winding and of which at least one of the support elements is a carrier roll. The other of the at least two support elements has a rigid carrier which guides the winding over a sheath arranged in a rotating manner around the carrier. A carrying shoe is combined with the other support element and acts hydrodynamically with respect to the sheath. The carrying shoe is provided with a concave bearing surface whose radius of curvature essentially corresponds to the maximum diameter (T) of the winding including the sheath wall thickness. The position of the carrying shoe can be adjusted as the diameter of the winding increases to reduce linear pressure on the winding allowing comparatively large diameter windings to be formed while avoiding the formation of disruptive spots or breaks in the winding.
