<p>An apparatus and method for manufacturing corrugated paperboard includes a heating section such as a plurality of steam heat chests (62) used in a double-facer for defining a heating surface. A take-up mechanism (35) is positioned downstream from the heating surface for advancing a corrugated paperboard sheet along a predetermined path of travel adjacent the heating surface. The take-up mechanism draws the corrugated paperboard sheet along the path of travel adjacent the heating surface (31). A plurality of flexible sheets (34) are positioned in side-by-side relation opposite the heating surface and transversely across the predetermined path of travel and longitudinally along the path of travel for slidably contacting and applying pressure to urge the advancing corrugated paperboard sheet against the heating surface so that heat is transferred from the heating surface to the advancing corrugated paperboard sheet. A support structure supports the plurality of flexible sheets in the position above the path of travel and includes movable support frames that carry the flexible sheets. The movable support frames are movable in a vertical direction to control the pressure applied onto each of the respective flexible sheets against the advancing corrugated paperboard sheet.</p> |
