Abstract

Mould-filling process, and apparatus for making profiled articles from pre-expanded thermoplastics masses. The mobile mass can be deformed and compressed, and the particles can be expanded. (a) The volume of the moulding space is first enlarged as desired, and after partly or completely filling the enlarged space, the volume is reduced to that required, by exercising pressure, on one or more mould faces to compress the moulding mass. The latter must not escape to the exterior, or penetrate between the mould parts. (b) After each compression the volume of the mould is again enlarged, and more moulding material introduced into the space.
