ABSTRACT An automatic clamp tightener utilizes a pivotally mounted air driven rotating tightener which pivots about a base via the inflation and deflation of a flexible diaphragm. Sensors are utilized to locate the tightener and sense when a clamp is to be tightened or loosened. Sensors also detect when the tightener is driven to a stall condition indicating that the clamp is tightened. The work piece is flattened via two hold down bars which move into and out of engagement with the work piece under automatic control to hold the work piece firmly in place and to pressurize same while the clamp is being tightened. The tightener and the automatic flattener are mounted on the same supporting frame which moves laterally along the location of the clamps to be adjusted.
