ABSTRACT:
An apparatus and method for processing elongated sheet material through a plurality of processing stations including a cooling station for lowering the temperature of the sheet material. The cooling station includes a plurality of individually controllable cooling zones each for controlling a portion of the transverse width of the sheet material during passage through the cooling zone. The cooling zones each include a plurality of cooling fluid directing spray nozzles and a sensor for sensing the temperature of the portion of the sheet material onto which cooling fluid has been directed by the respective cooling zone. A controller responsive to the temperature sensed at each cooling zone is operable for independently controlling the flow of cooling fluid to the fluid spray nozzles of each cooling zone based upon a preset temperature setting of the controller.
