Device for actuating clamping members of a turning device by remote control

The device according to claim 6, including bearing elements integrated in said control members.

In a sheet turning device of the type having components in the form of at least one turning drum, one storage drum with a toothed gear and adjustable toothed segments meshing with the toothed gear of the storage drum, and clamping elements operatively associated with the components, wherein the clamping elements are subjected to a pretension force and maintain a clamping connection between the toothed gear of the storage drum and another gear and, upon releasing of the clamping connection, the clamping elements allow an adjustment of the toothed gear of the storage drum relative to the other gear,

• a device for controlled operation of the clamping elements, the device comprising:
• a movable pressure rod and an energy storing device acting on said pressure rod for applying a biasing force on said pressure rod in a given direction,
• control elements associated with said movable pressure rod and a transmission element disposed between said energy storing device and said control elements, for transmitting forces between said energy storing device and said control elements, pressure means fluidically communicating with said control elements for actuating said control elements with a pressure medium and for moving said transmission element in such a way that clamping effects caused by said energy storing device are cancelled out.

In a sheet turning device of a rotary printing press, the turning device being of the type having components in the form of at least one turning drum, one storage drum and adjustable toothed segments meshing with the toothed gear of the storage drum, and clamping elements disposed on a sheet-carrying cylinder and at side walls, respectively, of the rotary printing press, the clamping elements being operatively associated with the components, and means for subjecting the clamping elements to a pretension force and for maintaining a clamping connection between mutually adjustable elements,

• a device for remote-controlled operation of the clamping elements, the device comprising:
• a movable pressure rod and an energy storing device acting on said pressure rod for applying a biasing force on said pressure rod in a given direction,
• control members operatively associated with said pressure rod, and pressure means acting on said control members for acting on said pressure rod opposite the given direction and overcoming the biasing force of said energy storing device.
