ABSTRACT:
A variable force exerting clamp assembly having a variable clamping area. A stretchable strap which deforms or "thins" to a smaller width in response to stretching is provided with a first work-engaging clamp secured at one end thereof and a second movable clamp which is slidable between the ends of the strap. The clamps are disposed for engaging a workpiece or workpieces between each other, and tension is applied until the strap is stretched to exert the desired force on the members, whereby, upon release of the tensional force, the strap tends to assume its original configuration, and the second clamp exerts a clamping force on the strap responsive to the strap expanding to its original width.
