A winding roll of a web to be wound or unwound by the apparatus is supported by the king rolls such that a press gap is formed with at least one of the king rolls. At least one of the king rolls has a support body and a shell made from a soft, elastic material, the shell having a plurality of cavities, the cavities opening in a direction opposite a peripheral surface of the support body. In one embodiment the supporting belt includes cavities which may be filled with compressible material. In another embodiment the supporting belt includes a cover layer and a base layer with the base layer being softer than the cover layer.
