ABSTRACT:
A method for continuously producing corrugated sheet from a supply of material having low melt strength at the forming temperature includes a heater, a pair of interdigitated thermo-forming rollers for corrugating the sheet as it exits the heater and a closely coupled calibrator at the outlet end of the thermo-forming rollers. A carrier maintains lateral tension on the sheet as it is heated, thermo-formed and calibrated so as to maintain its uniform lateral width. The thermo-forming rollers and calibrator form and maintain the corrugations until the material cools to below the glass transition temperature. A method for producing the corrugations is likewise disclosed.
