Title: METHOD AND APPARATUS IN CHANGING THE SETTING OF A SLITTER
Abstract:
The invention relates to a method in changing the blade setting of a slitter-winder, in which method the setting of blades (41, 42) is changing during slitting in order to slit component webs (Wo) of different widths, in which connection the width of the edge trimming which is formed changes and wherein an untrimmed neck remains between the edge trimmings of different widths which are formed when slitting according to a different blade setting. In the method, a cutting apparatus (50) is used for making a cut between the slitting line of an edge trimming according to an old blade setting and the slitting line of an edge trimming according to a new blade setting controlled by a control system (59) of the cutting apparatus (50). The invention also relates to an apparatus in changing the blade setting of a slitter-winder. The apparatus (50) comprises a cutting member (53) for making a cut between the edge trimmings of different widths produced in connection with the chnage of the blade setting in slitting, and a control system (59) for controlling the operation of the cutting apparatus (50).
