Abstract
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. A foot is mounted for movable relation relative to the frame in a direction substantially perpendicular to the surface. The pressure applicator is connected to a pressure device which biases the applicator away from the surface. The present invention also includes a variable pressure source connected to a control device for varying the pressure supplied to the pressure applicator that is ultimately applied to the surface.
