Abstract (en)
[origin: US2008202359A1] A press for crimping longitudinal edges of a plate for the manufacture of pipe has a closed press frame, an upper press platen, and a lower press platen extending longitudinally through the frame. A pair of transversely spaced and transversely shiftable upper supports are provided on the upper platen, and a pair of transversely spaced and transversely shiftable lower supports on the lower platen. Respective upper dies are fixed in the upper supports and have downwardly directed lower faces, and respective lower dies are fixed in the lower supports and have upwardly directed upper faces. A piston/cylinder assembly braced between the frame and one of the platens and pressurizable to shift the one platen vertically toward the other of the platens. Hydraulic actuators may position the holders and their dies transversely and also lock them in place.
