ABSTRACT:
A backing bar assembly has a plurality of positively positionable backing bar units which are retained within an inverted U-shaped housing by semi-cylindrical lifters which are adjusted by adjustment screws connected to the housing. Each backing bar unit has concave end surfaces which face the adjacent backing bar units. A pair of backing bar units is engaged by the semi-cylindrical convex surfaces of a lifter and may thus be vertically positioned by rotation of the adjustment screw. By adjusting two backing bar units at a single screw, dramatic discontinuities between backing bar units are avoided. An inflatable resilient seal is engaged by all the backing bar units and extends between the units and the blade to transmit force to the blade to retain it in a desired position.
