Abstract

The folding machine includes at least one pair of knife shafts, the knife shafts (22, 24) of which are, in a working position, mounted parallel to each other between two spaced-apart side walls (18, 20) of the folding machine (10). In order, in parallel with the production process, to be able to prepare knife shafts for a subsequent production process, the knife shafts (22, 24) are mounted in a cassette (28) which can be displaced through a sidewall (20) facing the operator from an inserted position, in which the knife shafts (22, 24) are in their working position, into a pull-out position, in which the knife shafts (22, 24) are outside the folding machine (10).
