Abstract

1,092,425. Laminates. IMPERIAL CHEMICAL INDUSTRIES Ltd. May 31, 1966 [July 12, 1965], No. 29437/65. Heading B5N. An apparatus for continuously manufacturing a laminate having a polyurethane foam core comprises means for transporting a sheet of facing material, means for dispensing on to the sheet a continuous layer of polyurethane-foam forming ingredients, a region thereafter in which foam formation may take place, means for blowing inert gas on to the surface of the foam to preserve tackiness, means for transporting facing material and contacting it with the tacky foam surface, means for exerting pressure on the laminate formed and means for curing the polyurethane foam. The inert gas is suitably air or nitrogen directed on to the surface of the foam at an acute angle opposing the direction of motion of the facing material. Edging strips may be placed along the lateral extremities of the foam core before the second sheet of facing material contacts the foam. The foam-forming materials may be dispensed from a mixing head fitted with a spray nozzle traversing the first facing sheet in a zig-zag pattern, and may be blown into a uniform layer by inert gas.
