Abstract
A coat weight control system for applying coating to a paper sheet in a paper machine permits even coating across the sheet with less actuator force needed. The system applies a specified force profile on a coating blade and has a plurality of actuators spaced apart, the actuators each applying a load. A flexible backing bar is positioned on the coating blade having connections there along to the actuators, the backing bar having a plurality of keyhole slots between the connections, the slots spaced apart along the bar.
