    • A system to achieve an improved winding structure while winding webs (1, 1', 1" . . . ), especially paper webs, to obtain at least one wound web roll (5, 5', 5" . . . ) on a winding machine, comprises sensors 8A, 9A for determining torque load 8 and rider roll nip load 9, respectively, in order to change the tension remaining in the wound web. The winding machine is of a supporting drum type with at least two supporting drums (2, 3), at least one of these supporting drums preferably has elastic flexible surface (2', 3'). The torque and nip loads 8, 9, respectively, for changing the tension remaining in the wound web roll operate such that the tension of the web (1, 1', 1" . . . ) first decreases at increasing web roll diameter of said at least one web roll (5, 5', 5" . . .) during an initial winding phase, then stays approximately at the same level and, after winding further, decreases further at increasing wound web roll diameter during a final winding phase.

    • In order to be able to manufacture large-caliber reels of high quality in a twin drum reel-up, the king rolls (11) and (12) have different diameters and are situated at different elevations. The main load of the reel is carried by the king roll (11), while the king roll (12) contacts the reel (13) with the smallest possible nip pressure which just suffices for transferring the torque difference required for generating the desired winding tension of the reel. The king roll (12) may be lowered as the diameter of the reel increases, namely depending on the fact if the winding shaft (13A) is displaced along a predetermined line of motion (14; 15), preferably a linear vertical or slightly tilted line of motion. An additional center drive which is made possible due to the aforementioned measures may additionally improve the winding result. A handling device (50) serves as a multifunction device for exchange of reels, in particular for the ejection of the reels, the clamping of the end of the web and the moving of the end of the web into the position for the next reel, as well as the separation of the finished reel from the web (1; 1', 1", . . . ).
