Claim:
Method for changing linear load on a reel-up which comprises an initial reeling device ( 9 ) having force devices, a reeling shaft ( 1 ), a surface drive apparatus, and a loading device comprising a loading actuator for a reeling process taking place after initial reeling, in which method the reeling takes place in the following way: the reeling begins as initial reeling in the initial reeling device ( 9 ) from which the reeling shaft ( 1 ) and the initial portion of the reel formed thereon is transferred to the loading device by means of which the stages following the formation of the initial portion of the reel are conducted, in such a manner that a part ( 8 ) of the loading device which transmits load to the reeling shaft ( 1 ) is brought in contact with the reeling shaft ( 1 ), the force devices of the initial reeling device ( 9 ) and the loading actuator of the loading device are primarily utilized to effect the linear load in the nip between the reel formed around the reeling shaft ( 1 ) and the surface drive apparatus, the linear load being adjusted during the reeling by means of the force devices and the loading actuator in such a manner that a desired linear load is attained as a function of given factors, characterized in that when the reeling shaft ( 1 ) is transferred from the initial reeling device ( 9 ) to the loading device, the contact of the part ( 8 ) that transmits load to the reeling shaft ( 1 ) takes place when the loading device is substantially in a state devoid of loading force, whereafter the loading by means of the loading device is started, and performed in such a fashion that the movement of the part ( 8 ) that transmits load to the reeling shaft towards the reeling shaft ( 1 ) is stopped before said part ( 8 ) enters in contact with the reeling shaft ( 1 ) located in the initial reeling device ( 9 ) and the reeling shaft ( 1 ) is allowed to move in contact with said part by increasing the diameter of the reel produced around the reeling shaft by continuously reeling the web on the reeling shaft ( 1 ).
