METHOD AND DEVICE IN A REEL-UP OF A PAPER WEB

摘要

The invention relates to a method in a reel-up of a paper web, in which the web roll (11) is formed around a reeling shaft and/or on support of carrier rolls or carrier belts, and in which a reeling drum (10) is used which forms a reeling nip (N) with the roll (11) to be produced. The reeling drum (10) is a deflection- adjustable reeling drum, the deflection of the roll shell (12) of which rotating around a central shaft is adjusted with at least one load means. According to the invention, in the method, the deflection of the roll shell (12) is adjusted internally of the shell (12) by loading provided with at least one load means (19) for providing nip force and/or nip-force profile prevailing in the reeling nip (N). In the method, the nip force and/or nip-force profile is adjusted with said at least one internal load means of the shell (12). The invention also relates to a device in a reel-up of a paper web. The invention relates to a method for manufacturing a roll, a reeling drum or equivalent which roll is crowned. A desired thickness profile/shape is turned in the shell of the roll from inside for providing the crown by means of inside pressurisation. The invention also relates to a nip roll/reeling drum of a paper or board machine, for crowning the roll shell (12) of which, the roll shell is arranged internally pressurisable and a thickness profile according to the desired crown is made to the roll shell (12) in the manufacturing phase.
