Abstract
An arrangement for the accurately positioned quick-action clamping and tensioning of printing plates on a plate cylinder (1). Clamping tools (14) are disposed in frame walls (2) and, after appropriate positioning of the plate cylinder, are engageable in coupling sleeves (12) on camshafts (4.3, 5.3) of front and rear tensioning bars (4, 5) by the application of pressure medium (15, 16, 17, 18). Clamping and unclamping is then effected by turning the clamping tools (14) via levers (20) and compressed air cylinders (23). A compressed air motor (25) is disposed in the cylinder gap (3) for tensioning purposes.
