ABSTRACT:
A method and apparatus for reel-up of a paper web, wherein a roll is formed around a reeling drum or in another embodiment of the invention on the support of carrier rolls or carrier belts, and wherein a reeling cylinder is used to form a reeling nip for contacting the roll which is to be produced during passage of the paper web through the reel-up apparatus, includes a center axis and a cylinder mantle mounted for revolution around the axle comprised by the reeling cylinder. A method and apparatus for reel-up of a paper-web includes hydraulic loading elements for adjusting deflection of the cylinder mantle such that distribution of line pressure in the reeling nip, in its axial direction is controlled, e.g. maintained to be substantially uniform.
