Abstract
A system for bringing the joint edges of first and second sheet metal components into butting relationship. The components are clamped in opposing clamping assemblies with one of the assemblies being movable toward and away from the other. A fluid motor is mounted on one clamping assembly and a piston extending therefrom is connected to the other clamping assembly through a pair of expandable bladders. By sequentially introducing high and low pressure air to first one bladder and then the other, the movable clamping assembly is caused to move one component toward the other while accommodating any initial misalignment between the edges.
