ABSTRACT:
A deflection loaded metering blade for contacting a metering roll in a RAM system. A thin metal (steel) leaf spring and holder the width of the fuser roll is used to support an elastomeric blade tip in contact with the metering roll surface. The relative mounting positions of the spring and metering roll result in an interference with each other thereby causing the spring to deflect and produce the required load. Thus, the loading and metering functions are separated, the former being accomplished by the spring and the latter being performed by the elastomer blade.
