This is the etching press in my studio (Copper Plate Press, Loveland, CO). It was made by Takach Press Corporation in Albuquerque NM. It has of a flat bed made of laminated wood, aluminum and high pressure laminate. Most presses use a steel bed. There is a large pressure roller, easily seen here. There is a second roller, identical to this one under the bed that actually moves the bed. The crank and reduction mechanism turn that lower roller. Finally, there are a set of pressure adjustment screws.In operation, the plate is placed flat on the bed, the paper placed on top of it and the bed of the press moves in between the rollers, pinching the plate and paper between them, applying the desired pressure.
On this particular press, the upper roller is 10″ in diameter. The upper roller is not driven, only the lower one, which in turn moves the press bed. The height of the roller over the bed needs to be adjusted precisely to control the pressure applied. This changes as the thickness of the plates, blankets and papers changes. The roller must also be exactly parallel to the surface of the bed or the pressure will not be even across the plate. The micrometer adjusters, one on each side, allow this to be controlled easily, precisely and repeatably.
