[origin: US6032506A] PCT No. PCT/BE97/00063 Sec. 371 Date Aug. 17, 1998 Sec. 102(e) Date Aug. 17, 1998 PCT Filed May 28, 1997 PCT Pub. No. WO97/46337 PCT Pub. Date Dec. 11, 1997A stamping press comprising a blank-holder force-regulating system using fluid-operated compensating cylinders (5, 7). The variation in the force in the blank-holder pressure-regulating areas is thus compensated so as to maintain a predetermined constant pressure in the conventional blank-holder area. This pressure in the conventional blank-holder area can, by virtue of the invention, according to certain alternative embodiments, also be made to vary.
