ABSTRACT:
A precision, fully controlled, metering-blade positioning system is achieved by providing dual, precision-constructed, direct, travel-distance measuring means interconnected in a closed loop with dual, blade movement drive motors and an information/movement controller. In the preferred embodiment, the dual, direct, travel-distance measuring means are mounted independently from each other at opposite ends of the blade, thereby assuring that each end of the blade is in the precise, desired position relative to a pre-set reference position. By independently, precisely positioning each of the opposite ends of the metering blade, the user is assured that the metering blade is in the exactly desired position, and in complete, precise parallel alignment along its entire length with a co-operating roller member.
