CONTINUOUS ADJUSTABLE BACKING BAR FOR PROFILING COATER BLADE FOR CONTINUOUS ADJUSTABLE FEATURE COATING BLADE

摘要

The backing bar assembly 20 includes a plurality of backing bar units (not shown) housed within the housing by semi-cylindrical lifters 68 that are adjusted by adjustment screws 60 connected to the inverted U-40). Each backing bar unit 40 has concave end faces 54 opposite the adjacent backing bar units. The pair of backing bar units engage with the semicylindrical convex surface 72 of the lifter and are vertically positioned by rotation of the adjusting screw. Therefore, sudden discontinuities between backing bar units can be avoided by adjusting two backing bar units with a single screw. The inflatable resilient seal 50 is engaged by all of the backing bar units and extends between the units and the blades to transmit force to the blades so as to maintain the blades in their desired positions.
