Abstract: In a process and a device for producing blocks of expanded polystyrene, a loose mass (7) of polystyrene spheres is expanded in a mold (2-3), where a rear surface (9) of the polystyrene block (8) previously produced delimits the mold forming chamber. Therefore, through adherence the newly formed block (7-8) is joined to the rear end (9) of the block previously formed, and the block (8) made in this way is fed forward until it forms the rear end (9) for another newly expanded block (8), and so on to produce a sort of continuous block (8), which can be formed for cutting to any desired size, without producing any waste.
