Abstract

An hydraulic press for pressing plastic mats reinforced with glass fibers into formed parts, which press has a stationary and a slidable cross-piece as well as a press drive which drive for driving the slidable cross-piece has at least one adjusting cylinder with a stroke length corresponding to the working range of the press and at least two couplable press cylinders of short stroke wherein for coupling each press cylinder to the slidable cross-piece a coupling rod and a clamping means is provided, the press being distinguished in that in order to better accomodate incorporation of the press drive into an existing press, each press cylinder has a hollow lifting body through which an associated coupling rod is guided, and for coupling the lifting body to the associated coupling rod a clamping device is included on the lifting body.
