Abstract

An apparatus for the manufacture of sheets of corrugated web of variable size comprises a margin cutting arrangement, which is disposed--in the conveying direction--downstream of, and separated from, longitudinal cutting arrangements and which is provided with cutting devices for cutting margins, which are permanently in engagement with the web of corrugated board. In the case of changes of format width accompanied by changes of the width of the margins to be cut off, this makes it possible that the latter can be cut continuously, which helps avoid malfunction.
