ABSTRACT:
Insulation board comprising a urethane foam core sandwiched between a thin flexible membrane and a thicker inflexible panel is made by dispensing foam forming materials onto a moving continuous sheet of the thin flexible membrane and depositing individual panel segments onto the foam as it expands. The manufacturing apparatus includes a conveyor press for transporting the flexible membrane past a foam dispensing device and means for consecutively depositing the individual panel segments onto the expanding foam. The panel depositing means comprise a suction apparatus for suspending the panel over the foam and a friction drive mechanism for simultaneously impelling a leading end of the panel against a trailing end of an immediately preceding panel to prevent the formation of gaps between consecutive panel segments. The resultant laminate is then passed through the conveyor press that acts as a forming and curing zone for the laminate which is thereafter cut to size at a cutting station.
