A flexible printing forme (2) is to be attached to the forme cylinder (1) of a rotary printing machine. For this purpose, the bent ends of the flexible printing forme (2) engage in a cylinder gap (3) which is fitted with a clamping and tensioning device. The latter comprises a rotatable flap (4) with a foot (5), through which the axis of rotation runs, and a limb (6) which is placed against said foot approximately perpendicularly and interacts with one end of the forme. An L-shaped support part (7) is screwed by its foot (8) firmly to the cylinder (1) and, with its limb (9), interacts with the other end of the forme. For clamping the bent ends of the forme in the region of the limbs (6 and 9), forme clamping springs (10) are used, which are provided with pressure surfaces in the region of the limbs. The limb (9) is elastically deformable by means of a setting screw (12) for readjusting purposes. Engaging on the tensioning flap (4) are compression springs (13), as a result of which the limb (6) is pressed against the forme clamping spring (10) for clamping and tensioning the printing forme (2). An eccentric spindle (14) by means of which the compression springs (13) can be tensioned and relaxed is used for releasing the printing forme (2). <IMAGE> |
