Abstract
A device for the cross perforation of webs, preferably paper webs for producing sacks, comprises a rotatingly driven perforating blade and a grooved roller, both of which are mounted on a machine frame and between them passes the web to be perforated. To adjust the penetration depth of the teeth of the perforating blade into the ring grooves of the grooved roller, there is at least one adjusting device for changing the distance between the axes of rotation of the perforating blade and the grooved roller.
