Abstract:
1. A master processing apparatus comprising: a frame; a first pressure applying roller; a second pressure applying roller, the pressure applying rollers being rotatable about parallel roller axes; a plurality of gears rotatable about respective gear axes parallel to the roller axes, the plurality of gears comprising: a pivot plate mounted for pivotal movement about the axis of the pivot plate gear; the first roller gear and the first pressure applying roller being connected to the pivot plate with their axes spaced radially from the axis of the pivot plate gear to permit a range of arcuate movement for the first pressure applying roller for adjusting a spacing between the first and second pressure applying rollers, the plurality of gears being configured to remain intermeshed throughout the range of arcuate movement for the first pressure applying roller; and a spring about the pivot plate gear axis for biasing the pivot plate and first pressure applying roller towards the second pressure applying roller, wherein the plurality of gears further comprises a second roller gear coaxial with and connected to the second pressure applying roller, the plurality of gears being intermeshed for simultaneous counter-rotation of both the first and second pressure applying rollers.
