Abstract
In the method in reeling of a paper or paperboard web, a web (W) is guided by means of a reeling cylinder (1) onto a reel (R) to be formed around a reeling axle (2). There are at least two reeling cylinders (1), both of which are used to reel in turn the web (W) onto the corresponding reel. The reels (R) are formed in turn in reeling stations located on opposite sides of the pair of reeling cylinders (1). The web (W) travels between the reeling cylinders (1) to either reeling cylinder (1) and the corresponding reel (R).
