Apparatus and method for applying variable pressure to a surface in corrugated paperboard manufacturing

摘要

An apparatus and method for applying variable pressure to a surface (22). The apparatus includes a frame secured to a fixed structure and located proximate to the surface (22). A foot (56) is mounted for movable relation relative to the frame in a direction substantially perpendicular to the surface. The pressure applicator (200) is connected to a pressure device (226) which biases the applicator away from the surface. The present invention also includes a variable pressure source (230) connected to a control device (232) for varying the pressure supplied to the pressure applicator that is ultimately applied to the surface.
