Abstract:
A paper machine for one of making and processing a fiber material web, said paper machine comprising:a plurality of rolls carrying the fiber material web, said plurality of rolls including a load roll and another roll defining a nip therebetween, the fiber material web traveling through said nip and defining a gore with said load roll on an approach side of said nip;a movable cutoff knife including a cutting edge positioned in said gore at a slight distance from said nip and adjacent to the fiber material web; andat least one impulse exchanger positioned in association with said cutoff knife, each said impulse exchanger being configured to transfer impulse energy to said cutoff knife to accelerate said cutting edge into colliding and thereby cutting contact with the traveling fiber material web, each said impulse exchanger being an impulse generator configured for transferring said impulse energy by impact of a striking force against said cutoff knife.
