Abstract
The present invention is directed to an apparatus and method for applying variable pressure to a surface. The apparatus includes a frame secured to a fixed structure and located proximate to the surface. The frame is in movable relation with a pressure applicator in a direction substantially perpendicular to the surface. The pressure applicator is connected to a pressure source. The pressure applicator contacts the surface. A mechanical compensator is mounted integrally with the pressure applicator to enable the pressure applicator to compensate for any variations in the contour of the surface. The present invention also includes a control device for varying the pressure supplied to the pressure applicator that is ultimately applied to the surface.
