Abstract

The present invention relates to a copy-carrying cylinder which has a peripheral surface (2) supporting sheet-like copies and which is provided with retaining elements for fixing the sheet-like copies in place on the peripheral surface (2). A folding device (5) which can be moved into and out of openings (4) at the peripheral surface (2) are bounded by at least one movable surface element (13). The surface element (13, 13.3) which is associated with the folding device (5) is designed in such a manner that it takes its closed position (22) automatically.
