A clamping mechanism for securing a cutting die board to a rotary support cylinder, including a double-acting pressure cylinder having a piston rod coupled to a clamping bolt which cooperates with a keyhole-shaped slot formed through the cutting die board, and an arrangement for supplying low pressure air to an extension chamber defined on one side of the pressure cylinder piston for controlling the magnitude of force applied to the bolt during extension thereof. In an alternate embodiment, a low-force releasable slip coupling connects between the piston rod and the bolt to control the extension force applied to the bolt.
