APPARATUS AND METHOD FOR APPLYING VARIABLE PRESSURE TO A SURFACE IN CORRUGATED PAPERBOARD MANUFACTURING

摘要

An apparatus (12) and method for applying variable pressure to a surface (10). The apparatus includes a frame (34) secured to a fixed structure and located proximate to the surface (10). A plurality of pressure applicators (200) are mounted on the frame (34). Each pressure applicator (200) includes a foot (56) in movable relation relative to the frame (34) in a direction substantially perpendicular to the surface (10). The foot (56) is connected to a pressure device (226) that biases the foot (56) away from the surface (10). Each pressure applicator (200) also includes a variable pressure source (202) connected to a control device (230, 232) for varying the pressure supplied to the pressure applicator (200) that is ultimately applied to the surface (10).
