Abstract: Fiber webs are wound into partial web rolls (15) in a winding device having at least two winding stations (20) and rider roll units (30) that load a pair of rider rolls (31,32) against the partial web roll (15) being wound. The partial webs (W1, W2) are guided to be wound to partial web rolls (15) around cores (14) via a nip between a winding roll (10) and the partial web rolls (15). The winding position of the partial web rolls (15) is on the upper circumferential half of the winding roll (10). The rider rolls (31, 32) are moved substantially linearly in the direction of the radius of the partial web rolls (15) and co-linear with a movement path of winding chucks (25) on which the partial web rolls are supported at the two ends of a core (14).

Abstract: The invention relates to a device for winding fiber webs, particularly paper and board webs, into partial web rolls, which device includes winding stations (20) for winding partial web rolls (R1 . . . Rn) via a nip between a winding roll (12; 13) and the roll being formed (R1 . . . Rn). The winding stations (20) are supported on a floor (25) or equivalent foundation and the mass of the roll being formed (R1 . . . Rn) forms at least part of the nip load of the nip between the winding roll (12; 13) and the roll being formed (R1 . . . Rn).

Abstract: The invention concerns a device in winding of a web. The device is composed of at least one loading and/or support unit (24) in order to support the winding core and to load the roll. The loading and/or support unit (24) comprises at least two rolls (22), around which at least one belt (25) has been fitted in the axial direction of the rolls (22). The rolls (22) in the loading and/or support unit (24) have been coupled together by means of coupling members (53, 54) so that movements of the rolls (22) in relation to one another are geometrically positively controlled.

Abstract: A method for winding a web onto a spool at least partially supported on a support roll in which the web passes through a nip formed between the support roll and a roll formed by the web winding on the spool. The roll being formed is loaded and/or supported by at least one loading/supporting unit which is/are displaced during initial winding stages in a direction substantially in a plane passing through a central axis of the support roll and a central axis of the roll being formed. Thereafter, the loading/supporting unit(s) is/are displaced in a direction substantially along a path parallel to a circumference of the roll being formed, and during final winding stages, the loading/supporting unit(s) is positioned to support the roll being formed from a bottom region thereof.

Abstract: A method and apparatus for winding a web onto a spool at least partially supported on a support roll in which the web passes through a nip formed between the support roll and a roll produced by the web winding on the spool. The roll being produced is loaded and/or supported by at least one loading/supporting unit which is/are displaced during initial winding stages in a direction substantially in a plane passing through a central axis of the support roll and a central axis of the roll being produced. Thereafter, the loading/supporting unit(s) is/are displaced in a direction substantially along a path parallel to a circumference of the roll being produced, and during final winding stages, the loading/supporting unit(s) is positioned to support the roll being produced from a bottom region thereof.

Abstract: A method and apparatus for cutting a paper or paperboard web particularly in a winder comprising at least one support roll (2) on which a roll (1) being wound is rotated. A curved, tensioned cutting blade (6) is rotated about the support roll (2) into the nip between the support roll (2) and the roll (1), whereby the sharpened and optionally toothed edge (9) of the blade cuts the web (4) being wound onto the roll (1) at a desired point.

Abstract: In an arrangement for forming rolls from a running web, the web is slit in its longitudinal direction and wound into a plurality of rolls, all having the same rotation direction during winding. The arrangement comprises means providing a peripheral as well as a central roll support force acting on the rolls during winding. The arrangement is so dimensioned that, due to the increase of the roll diameter during winding, the ratio of the peripheral support force and the central support force of a roll undergoes a substantial change merely as a result of the geometrical construction features of the arrangement. In the final phase of the winding of a roll, the central support force of the roll is considerably higher than the peripheral support force of the roll.
