Abstract
The method is for producing a first primary roll having a predetermined lateral surface defined by a diameter Df. The primary roll is made of material wound around a spindle. The material is used to produce smaller secondary rolls of material. The method comprises steps of (a) calculating a portion Sf of the lateral surface, which is covered by the spindle; (b) calculating a portion Si of the lateral surface, which represents material needed to produce the smaller secondary rolls of material: (c) calculating a compression factor K1 which is derived from a compression rate K of a previous second primary roll used to produce previous secondary rolls with respect to the previous secondary rolls; (d) calculating Df where:
