Abstract

In a reel change in the reeling process of a fiber material web, the fiber material web (W) running to a reel that is becoming full is changed to run around a new reeling core (2) brought to a reel change position in such a way that the web is made to adhere onto the surface of the new reeling core (2). The web (W) is made to adhere onto the surface of the reeling core (2) by a change in the properties of the material on the surface of the reeling core (2). The material is a combination of an adhesive area (6a) on the surface of the reeling core and a protective layer (6b) on top of the adhesive area, and the properties of the material are changed by removing the protective layer (6b).
