A rotary-blade folding unit includes at least one folding blade, a pair of folding rollers and a drive for producing a hypocycloid movement of the folding blade about a rotational axis of the folding blade and a main rotational axis for folding a signature that has been guided up to the rotary-blade folding unit in a transport plane extending between the main rotational axis and the folding rollers, and further includes a drive mechanism for producing an oscillatory movement of the folding blade at least approximately parallel to the main rotational axis; a folder including the folding unit; and a printing machine in combination with the folder.

Rotary-blade folding unit

The present invention relates to a copy-carrying cylinder which has a peripheral surface ( ) supporting sheet-like copies and which is provided with retaining elements for fixing the sheet-like copies in place on the peripheral surface ( ). A folding device ( ) which can be moved into and out of openings ( ) at the peripheral surface ( ) are bounded by at least one movable surface element ( ). The surface element ( ) which is associated with the folding device ( ) is designed in such a manner that it takes its closed position ( ) automatically.
