Device and method for cutting a material web

摘要

In order to prevent the tracks of ancillary substance from smearing when cutting a material web along predetermined cut progressions that lie between raised tracks of ancillary substance relative to the plane of the material web in the direction of a cutting roller, the web can be cut into segments with a predetermined segment length along the cut progressions by a cutting device. The device has a cutting roller, the angular velocity of which can be adapted to the web velocity for cutting the material web, and which can be accelerated and/or delayed between two consecutive cuts.
