Abstract

Continuous crosslinked thermoplastic foam strip Are produced by heating expansible, cross-linking thermoplastics under high pressure and subsequent relaxation, by the material being continuously fed into a pressure-resistant, heated mould by which the material, without friction, is conveyed further at a corresponding feed rate, and after leaving the mould is foamed by relaxation.
