Fiber web slitting method, involves rolling machine roll up to predetermined diameter in primary rolling station, and shifting machine roll from primary station to secondary rolling station during roll change of cutter

摘要

The method involves rolling a machine roll (15) up to a predetermined diameter in a primary rolling station (35.1). The machine roll is shifted to a secondary rolling station (35.2), and a machine roll change is implemented during connection of a fiber web (W) arriving from the new machine roll with a web arriving from an old machine roll that is connected with a splitting connection. The machine roll is shifted from the primary rolling station to the secondary rolling station during the roll change of a longitudinal cutter (1). An independent claim is also included for an arrangement for slitting a fiber web.
