Definitions
- the present invention relates to a plate clamping mechanism used for fastening a printing plate is used in an offset printing machine, and a method for the use of this mechanism.
- the present invention relates an apparatus and a method by which a conventional flat printing plate the mounting on the plate cylinder of the offset printing machine in a cylindrical Form is brought and clamped, thus the attachment and replacement of the To facilitate pressure plate on the plate cylinder.
- the cylindrically shaped and closed pressure plate is then through the cutout in the machine wall on the Plate cylinder moves, in such a way that the engaged with each other Ends are inserted into the axial slot in the plate cylinder. It a slot mechanism located in the slot is then actuated to the Fasten the pressure plate on the plate cylinder.
- a problem with the prior art device is that complicated and sometimes difficult to make bends at the ends of the pressure plate are around the plate ends during the application and fastening process hold together.
- the device includes a clamping mechanism which is removed from the plate cylinder and preferably again in an axial slot in the plate cylinder can be included.
- the axial slot can be provided with a device which holds the clamping mechanism after it is inserted into the axial slot, and which clamps the plate on the plate cylinder.
- the method according to the invention comprises the steps of removing the Clamping mechanism from the plate cylinder and opening of the clamping mechanism.
- the Both ends of a flat pressure plate are bent by approx. 90 °, then the Plate bent into a cylindrical shape.
- the bent ends of the plate, which after the cylindrical shape are approximately parallel to each other, are then in inserted the clamping mechanism.
- the clamping mechanism is closed, the ends of the plate being secured and the plate in its preformed cylindrical shape is held.
- the clamping mechanism holding the plate then becomes inserted as a unit in the axial slot of the plate cylinder.
- the plate cylinder has a series of compressed air openings on its circumference which when attaching the plate held by the clamping unit to the Plate cylinder is blown with compressed air.
- the compressed air causes a slight expansion of the Plate and creates an air cushion between the plate cylinder and the plate, what that Applying the plate to the cylinder is easier.
- the in the axial slot of the The plate clamping unit inserted is then secured to the
- the present invention does not require complicated bends Pressure plate ends to the plate when applied and attached in a cylindrical shape to keep. Therefore, the device of the present invention is considerably simpler to apply and facilitates the attachment of printing plates compared to the Prior art devices many times over.
