Abstract

The invention relates to a method and an apparatus for controlling the shrinkage of a fibre web. In the method the fibre web is transferred at a first transfer speed and at least one operation is performed on it. During the operation the fibre web is transferred at a second operational speed, which is lower than the first speed, or the fibre web is even completely halted for the duration of the operation. The fibre web is dried in a controlled manner before the operation is performed. The according to the invention comprises an operational unit, such as a slitter-winder and drying means arranged in the immediate vicinity of the fibre web for drying the fibre web. The drying means are arranged before the operational unit in the travel direction of the fibre web. The invention also relates to a method for rebuilding an existing slitter-winder or rereeler section in a paper machine.
