ABSTRACT:
Method for controlling the reeling of a web, in which the radius and/or any other corresponding quantity of the roll that is being formed, is measured by means of detectors with the signals thereof being passed to a control system. Adjusting signals controlled by roll diameter data measured on the basis of table and/or functional data stored in a memory of the control system for different radii of the roll, are formed in the control system by which a belt carrying member is controlled, this member being situated on an adjoining quadrant of the roll being would relative to a carrier roll. The supporting linear load of this belt carrying member is controlled by adjusting the tensioning of the supporting belt. The steps of the present method are carried out so that a suitable distribution of linear load in a reeling nip is carried into effect and so that the supporting and carrying linear loads of the roll being wound remain within preset limits.
