Patent ID: 7757990

Claim:
A method for changing a reel in a reeling process of a fiber material web, using a reeling core having a surface with an adhesive area covered by a protective layer on top of an adhesive area, comprising the steps of: passing the fiber material web to an old reel which is becoming full; bringing the reeling core into a reel change position in relation to the old reel; bringing the surface of the reeling core into a nipping contact with the fiber material web running on a surface of a web guiding member; while the reeling core is rotating in the nipping contact with the fiber material web running on the surface of the web guiding member, removing the protective layer on top of the adhesive area, exposing the adhesive area to form an exposed adhesive area on the surface of the reeling core; changing the fiber material web from passing on to the old reel to winding on to the reeling core by adhering at least a portion of the fiber material web to the exposed adhesive area of the reeling core; forming a tongue in the fiber material web before the nipping contact so that the forming of the tongue is synchronized with the exposing of the adhesive area so that the exposed adhesive area hits an area of the tongue when the exposed adhesive area first passes through the nipping contact, adhering the tongue to the reeling core; and wherein a location of the adhesive area is detected during the rotation of the reeling core, and the forming of the tongue in the fiber material web before the nipping contact is synchronized with the location of the adhesive area.
