ABSTRACT:
To position two relatively rotatable elements, for example folding jaw control elements of a folding jaw cylinder of a rotary printing machine, with respect to each other, and re-position the elements, a positioning drive (7), for example a motor coupled to a gear, which is coupled for rotary transmission to an axially movable shaft or rod element (10, 10'), movable, for example, under fluid, preferably pneumatic pressure. When projected, the coupling element is engageable with a positioning gear (12) on one of the elements (22) and, upon rotation of the element by the positioning drive, can effect re-adjustment of the angular position of the other element, upon engagement with a positioning gear (11) coupled thereto. The arrangement permits remote positioning and indication of relative position by a feedback transducer (13, 113), such as a potentiometer, which can provide position signals suitable for a display (B).
