ABSTRACT:
A double wall plastic article and a method and apparatus for forming a double wall article with a pair of deformable thermoplastic sheets wherein the sheets are mounted, in face to face contiguous relation, on a single pair of laterally spaced longitudinally extending rails. The rail supported, contiguously disposed sheets are heated to forming temperature and are then subjected to differential forming pressures via a pair of opposed molds which seal to the sheets to fuze perimetrically extending, opposed portions of the sheets and form the border of the article being formed. Differential pressure is then applied to a central portion of at least one of the sheets within the formed border to withdraw the central portion and form the article.
