Abstract: An apparatus and method for applying variable pressure to a moving surface, such as a moving web of corrugated paperboard. The apparatus includes a frame secured to a fixed structure and located proximate to a heated platform. A number of pressure applicators having movable pressure-applying feet are mounted on the frame. The moving surface moves between the heated platform and the feet of the pressure applicators. The pressure-applying feet are movable in a direction substantially perpendicular to the moving surface. This allows the pressure-applying feet to press the moving surface against the heated platform as the moving surface moves between the heated platform and the feet of the pressure applicators. Each pressure applicator may be independently controlled, typically by an inflatable air bladder, to apply variable pressure to the moving surface.

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.
