ABSTRACT:
The invention contemplates an improved folding machine for providing different types of folds. The machine includes a folding knife mechanism which is rotatably mounted in the machine frame about an axis of rotation which lies in the plane of the sheet to be folded so that at a first position the knife operates upwardly and at a second position the knife operates downwardly. These different directions of operation will produce different types of folds without the need of different folding mechanisms for each type of folds.
