Presses, using a press ram, characterised by the features of the drive therefor, pressure being transmitted directly, or through simple thrust or tension members only, to the press ram or platen
Definition statement
This subclass/group covers:

Presses using a press ram characterised by the features of the drive therefor in general and also those presses using a press ram characterised by the features of the drive therefor, for particular purposes, which are not provided for elsewhere. The driving system is decomposed, if necessary, in simple fluid actuation units (e.g. a cylinder/piston) and simple mechanical force multipliers (e.g. a lever, a toggle, a screw/nut system).
