    Abstract: In a recording medium transporting mechanism, a flange member is attached on either side of a roll paper and the flange member has a diameter smaller than a maximum outer diameter of a roll paper. Support rollers support a corresponding one of the flange members in a rotatable manner. The support rollers are moveable along the axis of rotation of the roll paper. The sum of an outer diameter of corresponding one of the flange members and the support rollers is greater than a maximum outer diameter of the roll paper. A rewinding roller of at least a length equivalent to a distance between both sets of support rollers when the sets of support rollers are farthest apart is engaged with a support roller within the set of support rollers and can rotate the flange member in a rewinding direction over a desired amount of continuous time.

    Abstract: A core locking device has members (25) for locking the device (17) to a winding core of a roll to be wound on a two-drum winder, advantageously to a core. The device (17) is placed on a slide arranged in connection with the two-drum winder, and moves, as winding progresses, with the center of the roll being formed along the slide. The device (17) has an actuator (20) to produce a counterforce for the force caused by the mass of the core locking device (17) in the changed position of the core locking device (17).

    Abstract: The present invention relates to a w winder (1) for winding a web roll (2) from a fibrous web such as a paper web or a web of non-woven 12 material paper (2). The winder (1) comprises two support rolls (3, 4) for supporting the web roll (2) during reeling and a core shaft (5) for winding the paper reel (2). At each longitudinal end of the core shaft (5), there is a carrier chuck (6) in which the core shaft (5) is rotatably journalled. The carrier chucks to are arranged to be movable in a frame towards or away from the support rolls (3, 4) and a rider roll (8) is arranged to be capable of acting against the web roll (2) being wound. The rider roll (8) is carried by a rider roll beam (9) and the rider roll beam (9) is arranged to be movable in the frame (7) such that the rider roll (8) can be moved towards or away from the support rolls (3, 4). There is at least one actuator (10) for moving the rider roll beam (9) towards or away from the support rolls (3, 4); and at least one load cell (12) arranged to detect the force between the rider roll (8) and the web roll (2). The winder (1) also comprises at least one actuator (11) for moving the carrier chucks (6) of the core shaft (5) independently of the rider roll beam (9) and the winder (1) comprises at least one load cell (13) arranged to detect the force with which the carrier chucks (6) act on the core shaft (5). The winder (1) also comprises a logic control system (14) connected to the load cells (12, 13) such that the logic control system (14) receives measured values for the force between the web roll (2) and the rider roll (8) and the force with which the carrier chucks (6) act on the core shaft (5). The logic control system (14) is programmed to control movement of the carrier chucks (6) and the rider roll beam (9) such that the sum of the forces detected from the load cells (12, 13) and the force resulting from a calculated weight of the web roll (2) corresponds to a set value for the force between the web roll (2) and the support rolls (3, 4). The invention also relates to a corresponding method for operating the winder.

    Abstract: A sheet winding mechanism includes a detachable winding core, a rotating body coupled to a first end portion of the winding core to rotate the winding core, and a non-rotating body against which a second end of the winding core is pressed. The winding core includes a winding core main body, a first portion which is located at the first end portion and is coupled to the rotating body, a second portion which is located at the second end portion, is movable in the axial direction, and presses against the non-rotating body, a first elastic body which urges the second portion outward along the axial direction, and a sheet holding portion configured to hold an end portion of a sheet. When the rotating body rotates the winding core while the sheet holding portion is holding the end portion of the sheet, the sheet is wound around the winding core.
