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. Alternatively, several pressure applicators may be grouped into commonly regulated zones so that each zone of pressure applicators is independently controlled to apply variable pressure to the moving surface.
