  • Pneumatic pressure pad for cyclical even application of pressure forces, particularly for contact duplication
    Patent number: 5113219
    Abstract: A pneumatic pressure pad within an exposure stage of a microfiche duplication equipment cyclically reliably evenly progressively pressures a microfiche master film into uniform pressured contact with an unexposed film in order that the unexposed film may be exposed from the master film without appreciable distortion. A housing of the pneumatic pressure pad defines a chamber divided into separate volumes by a flexible diaphragm. A pneumatic source cyclically applies a differential air pressure between the chamber's two volumes and across the flexible diaphragm. Outside of the housing, an elastomeric pressure pad presents a substantially planar precision crowned surface in a direction oriented towards the planes of each of the unexposed and exposed films. A shaft connects the diaphragm to the pressure pad.
