Method for fastening a flexible plate

A method for clamping and releasing flexible plates positioned on a cylinder including:

• providing first and second cylinder grooves in the cylinder with each said cylinder groove having a front edge and a rear edge;
• providing first and second suspension slits on a peripheral surface of the cylinder and locating said first and second suspension slits radially outwardly from said first and second cylinder grooves;
• using said cylinder groove front edges to define said suspension slits;
• providing a front plate suspension leg clamping device and a rear plate suspension leg clamping device in each of said first and second cylinder grooves;
• providing a first actuating device in said first cylinder groove and a second actuating device in said second cylinder groove with each of said first and second actuating devices being selectively operable to exert first and second different levels of force against said front and rear plate suspension leg clamping devices;
• operating said first and second actuating devices during a first unclamping sequence for releasing only a first one of the flexible plates positioned on the cylinder including exerting said first level of force using said first actuating device for releasing a rear suspension leg of the first plate by opening said rear plate suspension leg clamping device in said first cylinder groove;
• retaining a front suspension leg of a second plate positioned in said first cylinder groove during release of said rear suspension leg of the first plate during said operation of said first actuating device at said first level of force;
• releasing a front suspension leg of the first plate by operating said second actuating device and exerting said second level of force and opening said front plate suspension leg clamping device in said second cylinder groove;
• and
• retaining a rear suspension leg of the second plate in said second cylinder groove.
