ABSTRACT:
In a method and an apparatus for controlling reeling used in connection with the making of paper/board/some equivalent web-like material, a reeler is used in the reeling which has a reeling element (2), a reeling core (T), around which the web (W) is reeled to form a reel (3), as well as elements for loading the reeling core (T) and the reeling element (2) against each other in order to bring about a reeling nip (N) in between the reeling element (2) and the reel (3). The reeling is monitored by a detection apparatus, which automatically detects any events differing from normal reeling.
