<p>Method and device for the production of expanded polystyrene blocks, comprising expansion of the loose mass (7) of polystyrene spheres within a polyhedral mould (2-3), one face of which is formed by the end surface (9) of the previously produced block of polystyrene (8), bonding the newly expanded block (7-8) to this end (9)as one and the same substance, advancement of the block (8) until it becomes an end (9) for another block, and so on, thus producing a continuous block (8) which can be cut to any size without generating waste or scrap.
