Definitions
- the invention relates to a device for tensioning a printing plate on a plate cylinder from Rotary printing presses with one in a channel of the Plate cylinder arranged clamping device for that trailing plate end that holds a shaft for Clamping elements with bolts mounted on them to accommodate Clamping elements for clamping angled and not has angled plate ends, with tension springs on the tensioning and clamping elements act and with Pneumatic units for relaxing and releasing the plate end, lugs on the clamping elements on a projection Support on the plate cylinder.
- the tensioning device for the Pressure plate end when clamping angled and not angled plate ends of printing plates and printing foils to simplify and tighten the pressure plate ends optimize.
- the Clamping elements are sprung top grippers that are attached clamp non-angled printing plates or foils and that the tension springs between the plate cylinder and Clamping elements are arranged and their clamping force between the shaft for receiving the clamping elements and the bolts for Recording the clamping elements is directed.
- the tension springs between the plate cylinder and Clamping elements are arranged and their clamping force between the shaft for receiving the clamping elements and the bolts for Recording the clamping elements is directed.
- An advantageous embodiment is characterized in that that the sprung top gripper is a rigid gripper part and have a spring part. With this solution the Clamping force of the top gripper on the special needs be aligned.
- Another advantageous embodiment of the invention is characterized in that between the tension springs on Plate cylinder clamping screws are arranged on the Top gripper to increase the clamping and clamping force of the Clamping device are adjustable. With these tension screws is both the clamping force and the clamping force on the pressure plate end acts to increase so that regardless of whether an angled or non-angled pressure plate is used, for example an axial stretching of the trailing plate end is possible. Of course these tensioning screws must be turned back when a Relaxation or loosening of the plate end can be carried out should.
- a channel 1 of a plate cylinder 2 is one Clamping device 3 for the trailing plate end 4 provided with which the pressure plate 5 on the lateral surface of the plate cylinder can be clamped.
- clamping elements 7 are attached to the Clamping elements 7 .
- clamping elements 9 with which an angled plate end 4 in connection with the clamping element 7 can be clamped.
- pneumatic units 10 provided that can act on the clamping element 7 (Fig. 2), so that the clamping element 7 against the Is rotated clockwise and approaches 11 to the Clamping elements 9 on a projection 12 on the plate cylinder support. This opens the at the same time Clamping element 9 so far that the pressure plate 5 is removed and a new printing plate is easy to insert.
- the top gripper 13 for Example made of spring steel and on their Gripping area opposite end on the clamping element 9 attached.
- the top grippers 13 can be formed in two parts be with a rigid gripper part 14 and a spring part 15.
- the spring part 15 is also here via screws 16 the clamping element 9 attached.
- This is also supported rigid gripper part 14 on a system 17 on the clamping element 9 from so that high clamping forces with the rigid gripper part 14th transferred to the non-angled printing plate end 4 can be.
- the Clamping force of the tension springs 18 thus causes the closing of the Clamping element 9 and then tensioning the clamping element 7.
- the clamping element 9 is counterclockwise rotated and the clamping element 7 clockwise. It is sufficient thus a series of tension springs 18 around both functions to execute.
