Abstract:
A method for processing moving paper webs comprising:providing a pressing device having supports for a rail-like pressing tool and for a cooperating counter-pressing tool;positioning said pressing device transverse to a direction of travel of a moving paper web;providing a vibration generator in at least one of said supports for said pressing tool and for said cooperating counter-pressing tool;operating said vibration generator;causing at least one of said pressing tool and said counter-pressing tool to vibrate in a direction toward and away from a surface of said moving paper web in response to said operation of said vibration generation;passing said paper web between said pressing tool and said counter-pressing tool;exerting a pressure on said moving paper web in said pressing device along an intended transverse fold line by means of said vibrating pressing device;forming creases in said moving paper web in said pressing device by using said vibrating pressing device;subsequently transversely cutting said moving paper web into signatures; andfolding said signatures transversely along said intended transverse fold line.
