Abstract
For the cutting of a web a circular cutter is journaled rotatably in a slide which is moved along the cutting line by means of a linear drive. The cutter has a disk-shaped base body journaled freely rotatable which upon its perimeter is provided with pointed cutting blades angled in the sense of rotation. The distance of the base body from the web is chosen such that only the cutting blades but not the base body penetrate the web. Furthermore, the cutting blades are so fashioned and arranged that upon their penetration of the web to the maximal depth of penetration, an uncut portion remains between two cutting blades which upon exit of the subsequent cutting blades is severed by their leading cutting edge.
