ABSTRACT:
A machine and method for manufacturing corrugated board, including several machines for applying heat to both sides of the corrugated board during the manufacturing process. Different types of heat exchangers may be used on the top and bottom sides of the moving surface to transfer sufficient heat to the moving surface, to remove moisture and to cure the adhesive of the corrugated board. Independently controlled heat exchangers enable the manufacturer to regulate the heat applied to the corrugated board across the width of the machine and in the direction of the machine flow, in response to varying the desired width and thickness of corrugated board. Unused areas of the hotplate section may be isolated to minimize the heat loss in the machine when narrow width corrugated board is manufactured.
