A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

A paper rewinding machine includes a rewinding assembly operable to produce coreless retail paper rolls.

A winding machine for winding a finishing roll having a radius R of a sheet material on a core having a radius r.sub.c is provided. The winding machine includes: a support drum assembly arranged on a first side of the finishing roll and configured to support the finishing roll from the first side; a rider roll arranged on a second side of the finishing roll opposite to the first side and configured to apply a first nip pressure onto the finishing roll from the second side the finishing roll being supported by the support drum assembly; and a control unit configured to adaptively control the second nip pressure applied by the rider roll onto the finishing roll depending on an ascent rate of the rider roll.

A device and method of winding a web (W) of tissue paper or a non-woven material onto spools (2) to form a succession of web reels (3) on the spools (2) wherein the force in the winding nip (5) is measured and, as the diameter of the web reel (3) grows, the spool (2) on which the web reel (3) is wound is moved during winding along a horizontal plane such that, in the horizontal direction, the distance between the first supporting drum (4) and the spool (2) increases, and the second supporting drum (9) is moved vertically downwards to match the increasing size of the web reel (3) while maintaining contact with the web reel (3) to such an extent that a nip force between the web reel (3) and the second supporting drum (9) is maintained, and the first supporting drum (4) is moved vertically downwards as the diameter of the web reel (3) grows and moved to such an extent that the measured nip force in the winding nip (5) remains substantially at a set value or within the range of a predetermined upper and a predetermined lower value.

A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.
