ABSTRACT:
Apparatus for cross cutting and/or perforating of a web. The apparatus performs two consecutive partial cuts and, provides for positive guidance of a partially cut web. This is accomplished by first and second cutting blade rollers, arranged with one common counter cylinder and guided by groups of belts passing through breaks in the blades. The breaks of the two blades are laterally offset relative to each other, and the belts are pressed against the counter cylinder to convey the web. This eliminates the need for one counter cylinder and one pair of pull rollers, it decreases the danger of web tear and eliminates the web stretching and the accompanying offset of the two partial cuts.
