ABSTRACT:
A clamp secures a workpiece relative to a work piece support. A clamp arm is connected to an external end of the clamp for movement between workpiece clamping and release positions. An inflatable bladder disposed within a bladder support is releasably attached to the clamp arm between the workpiece and the clamp arm. A proportional regulator controls the inflation of the bladder, so that when the bladder is inflated, the bladder provides uniform distribution of the pressure to be exerted along a greater portion of the workpiece to protect the workpiece surface from undesirable indentations or defects.
