To provide close coupling between movable elements, such as segments (18) capable of varying the effective diameter of a folding blade cylinder (2) or a movable jaw (38) of a folding jaw cylinder, a first gear gear element (21, 47) is coupled via a positioning spindle (20, 43) to the respective movable element (18, 38); a second gear element (22) is coupled to the spindle (20, 43) and further rotationally coupled to the cylinder shaft (11, 35). A positioning or adjustment gearing, for example a differential, or a planetary gearing is positioned in close vicinity to a side wall of the machine, facing the respective cylinder, the positioning gearing being operable to be controlled to change the relative angular relationship between input or received rotation and output or delivered rotation, and being coupled to the second gear element (22), to receive rotation therefrom and further to the first gear element to deliver rotation and additional adjustment movement thereto. The adjusting gearing, which superimposed adjusting or positioning movement, is controlled by a positioning control element, such as a hand wheel (not shown), or a remote positioning control motor (30) coupled thereto by a gear, and controlled, for example, by a suitable electrical-electronic control unit, which can receive input data relating adjusting movement to, for example thickness of paper products being folded, number of paper products in a stack, and the like.
