Abstract (en)
[origin: US4357006A] This is a vacuum clamp for holding workpieces which assures that the workpiece is held without distortion. This is accomplished by providing a fixed support, with a convex surface, and a flexible seal around the fixed support so that when a vacuum is drawn within the seal the workpiece being held abuts the fixed support tangentially. The convex surface of the support does not force the workpiece to conform to the surface of the support as it would if the surface of the support were flat.
