  • Patent number: 4494455
    Abstract: A device for aiding in preparing a die member of a platen press to have recesses in registry with tools of a punch member characterized by a pressing station having an upper and lower bolster for receiving a pressure-forming device and a stack including at least one backup member, a die member and the punch member so that as the pressure device acts on the stack at least the outline of the tools of the punch member is transferred to a surface of the die member. The pressure device utilizes a hydraulic plate having a recess covered by a membrane which membrane is engaged by flexible support blades or members on its outer edge which are held there by an outer frame formed of blade guides. The device also includes a transport arrangement for moving the stack between the pressure station and an unloading station.

  • Patent number: 4466318
    Abstract: A drive system for the cutting station in a platen press has four toggle joints supporting the platen and each having a cam follower for moving the toggle joint by an associated rotating cam. The four toggle joints are disposed in pairs perpendicularly to the transport direction of sheets in the press. The pairs of toggle joints are aligned, with one pair of toggle joints being disposed between the other pair. The toggle joints are connected to a release device controlled by a security coupling. The cams are mounted on a common shaft provided at one end with a braking mechanism. Declutching of the security coupling simultaneously commands operation of each release device and of the braking mechanism.
