ABSTRACT:
Metal foil is applied to sheet metal by a film of polythene adhering to both and separating the two from direct contact, for improving the heat-insulating qualities of the sheet metal, by superimposing the film on the sheet metal, superimposing the foil on said film, and drawing the laminated assembly under tension along a convex curved surface, said foil next to said surface, and simultaneously heating said sheet metal to heat, by conduction, said film, heat and pressure on said foil causing it to bond to said foil and said film.
