Abstract
A device for adjusting a rotational position between coaxial fixed and adjusting gears and for changing-over a gripper by axially displacing an adjusting member on a cylinder of a turning device of a sheet-fed rotary printing press, includes a pressure member for effecting a spring coupling of the gears via a radially extending pressure lever. An adjusting member which reduces the spring force is axially displaceably guidable on the cylinder and becomes effective upon the pressure member only after traversing a distance for actuating a switch of an electrical safety device in a power supply circuit of a driving device. Another electrical safety device is between control positions of the adjusting member for interrupting the supply circuit to change over the gripper control. A connecting rod is axially displaceably guided in the cylinder and a spring which produces the spring force is in operative engagement with the pressure member for exerting the spring force thereon and is braced against the connecting rod. At least one clamping member is disposed in the adjusting member for changing-over the gripper control, and intermediate members, are provided, via which the one clamping mem…
