The folding machine has a cross fold module which includes a cross-fold folding blade (), a sheet-supporting device () which is arranged below the cross-fold folding blade () and on which an incoming sheet comes to rest, and a roller frame () which is arranged below the sheet-supporting device () and into which a sheet is introduced by the cross-fold folding blade (). A three-fold module () with a three-fold folding blade () arranged perpendicularly with respect to the cross-fold folding blade () is arranged downstream of the roller frame (). The three-fold module () and the roller frame () are arranged on a rotary stand () which is rotatable through at least 180 about a vertical axis ().

The holding-down arrangement for holding down a sheet () in a sheet-bearing region of a sheet-processing machine, in particular of a folding machine, includes a plurality of blowing devices () which, during use, are directed toward a sheet () and direct an air jet () onto the sheet (). The holding-down arrangement may be fitted in a sheet-aligning device which is arranged downstream of a sheet infeed and includes a sheet-bearing device (), on which an incoming sheet () comes to rest.

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