Abstract
Method and apparatus for the metallization of support members, such as paper sheeting and other cellulosic products. A metallic film is transferred to the paper support from a cellulosic carrier and adhered to the paper by a thermoplastic material. The cellulosic carrier, with a releasably adhered film of metal, is brought into contact with a paper support and an intervening thermoplastic adhesive. Pressure and/or heat is applied to the composite which is subsequently cooled and the carrier stripped away to leave the desired metallic layer on the receiving surface of the paper support. This transfer procedure overcomes the objections associated with plastic carriers and is particularly suitable for metallizing support members, like paper, which are otherwise difficult to metallize.
