ABSTRACT:
An improved hydraulic press has a hydraulic die that is pulled to move along a work path relative to the hydraulic press by a moving coil of material. After movement the hydraulic die engages the hydraulic press and the two begin to move together. With this arrangement, the moving material only need initially overcome the inertia of the hydraulic die. The moving hydraulic die has momentum when it engages the hydraulic press, and that momentum assists in overcoming the inertia of the relatively heavy hydraulic press. A relatively thin sheet material can thus be utilized to move both the die and hydraulic press.
