A relatively simple press for producing oriented strand waferboard includes a first endless conveyor for receiving a mixture of wafers and resin to form a wafer or strand oriented mat, which is carried into a press including a second endless conveyor above and spaced from the first conveyor for defining a mat receiving gap, a pair of endless chain assemblies within the conveyor loops for applying heat and pressure to the mat, each assembly including contiguous, pivotally interconnected containers which are filled with a liquid so that the containers can be heated by catalytic heaters located within the conveyor loops on the sides of the chain assemblies opposite the mat receiving gap, and a plurality of rows of rollers in the endless chain assembly for applying uniform pressure to the mat. The sheet of waferboard produced by the press can be used as is, or by the use of suitable adhesives remain in a plastic condition for corrugation in forming rollers. Closed, triangular corrugations can be produced by feeding the already partially corrugated, still flexible board through an extruder where longitudinally extending, closed triangular corrugations are formed. The corrugations can be filled with a foam insulation before being discharged from the extruder, and one side of the corrugated panel coated with plaster to produce an inside finished, insulated wall panel. |
