Abstract
An automatic clamp tightener utilizes an air driven rotating tightener which is suspended on a plate. The plate is caused to slidably move inwardly towards the clamp to be tightened and to be withdrawn therefrom. A laterally movable carriage supports the tightener and the suspension plate. The tightener employs mechanic stops for end-left and end-right of the carriage to limit motion of the carriage. The motor driving the carriage bearing the suspended tightener may be either a stepping motor or a servo motor. The air driven tightener is powered to open or tighten a clamp for either a predetermined period of time or until a predetermined tension or strain is sensed in the clamp.
