Abstract: PURPOSE: To keep a maximum nip pressure depressed on a winding roll to predetermined value or less by fixing tension-controllably a belt looped over two mounted support drums and contacting a rider roller to the winding roll with nip-contact upon start of winding the support drums. CONSTITUTION: A loop belt is wound around a pair of support drums 12 and 14 positioned horizontally at some intervals and a belt-tension-roll 18 positioned under these drums 12 and 14, and each support drums 12 and 14 are rotated by driving motors 20 and 22 in the direction of arrows 28 and 30. A core 10 is supported in a notch between the support drums 12 and 14 and a web sent out from a paper-making machine is wound around the core 10. A rider roll 40 provided on the core 10 is movablly contacted to a wound-roll wound on the core 10 and is vertically moved in translation against the winding roll as the diameter of it increases.
