Abstract
An apparatus for producing thick slabs of thermoplastic synthetic-resin material comprises a pair of extruders each extruding a half-slab strand to a respective roller assembly, the roller assemblies having final rollers which form a consolidation nip between them in which the two half slabs are bonded together. Preferably the half slabs and the roller assemblies are mirror symmetrically constructed and the half slabs can be formed with longitudinal compartments which can be filled with a foamed synthetic-resin material.
