  • Patent number: 5863369
    Abstract: There is provided architectural molding apparatus including a supporting frame assembly and a paper roll assembly which delivers a continuous paper web via tension and drive rollers to an adhesive applicator where hot melt pressure sensitive adhesive is deposited on the web. The glue coated paper web passes over roller to a profiled polystyrene core at a set-up roller assembly. The core is delivered by a core feed assembly which is adapted to receive lengths of the core in abutting relation. The set-up roller assembly receives the core and urges the paper web glue side first into the core to form the molding assembly which passes to a laminating roller assembly adapted to urge the glue covered web into intimate contact with the profile face of the core. The molding assembly then passes to a series of rollers adapted to progressively fold and roll the web to completely wrap the core.

  • Patent number: 4009146
    Abstract: A coating mixture for use in aluminizing metal surfaces comprises 5 to 50% by weight of an organic resin binder, 2 to 25% by weight of one or more halides and the balance finely divided particles of an aluminium-containing alloy. The alloy has a melting point of at least 1100.degree. C and contains 40 to 60% by weight of aluminium, the balance comprising iron, cobalt, nickel or zirconium or any combination thereof. The coating mixture is applied to the metal surface to be aluminized and then heated in an inert or reducing atmosphere at a temperature of 800.degree. to 1100.degree. C for a time sufficient to enable at least some of the aluminium in the alloy to diffuse into the metal surface.
