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.
