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.

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.

1. An apparatus for producing blocks of material for producing a building structure, the material being an expanded polystyrene, the apparatus comprising: means for forming a working block including the material;means designed for forming the working block by a plurality of forming steps;means for obtaining a predetermined block of material from the working block comprising means for separating the predetermined block from the working block;a mold configured to form a basic block of material that is adhered to a previously-formed block to form the working block, the mold including a forming chamber defined by a plurality of lateral walls and a rear wall, the forming chamber being open at a front thereof, in the forming chamber, the previously-formed block includes means for closing a front opening of the forming chamber during a dwell step of forming the basic block, the basic block being formed by the forming chamber receiving the material that is fed into the forming chamber and receiving a working fluid that is fed into the forming chamber to cause expansion and reciprocal adhesion of polystyrene spheres of the basic block and adhesion of the basic block to the previously-formed block; andmeans for cutting the predetermined block from the working block in a dwell condition in which the working block is partially disposed within the mold and partially extended from the mold, the means for cutting comprising a supporting frame and a cutting element moving between a raised and retracted position and a lowered and forwarded position relative to the supporting frame to provide a plurality of predetermined blocks having variable lengths,wherein the means for cutting is longitudinally movable relative to the mold on a corresponding track or guide extending longitudinally parallel with a supporting surface for the working block to a respective longitudinal distance relative to the mold at which the predetermined blocks are cut to a predetermined length during the dwell step of forming the basic block, and the respective longitudinal distance of the cutting means from the mold being selectively modifiable to produce varying lengths of the predetermined blocks, andwherein a movement of the cutting element is coincident with formation of the basic block of the material in the mold and adhesion of the basic block to the previously-formed block. 2. The apparatus according to claim 1, further comprising means for adding the basic block of material to the working block, by forming the basic block in contact with a rear end of the working block. 3. The apparatus according to claim 1, wherein the mold has a door which is configured to open. 4. The apparatus according to claim 1, wherein one of the lateral walls of the mold can move between a position in which the mold is closed and a position in which one or more of the working block of material, the predetermined block of material, and the basic block of material being released, allowing the one or more blocks of material to be fed freely. 5. The apparatus according to claim 1, wherein the means for cutting comprises a supporting frame. 6. The apparatus according to claim 5, wherein the cutting element is configured to move to a forward position for cutting the material. 7. The apparatus according to claim 5, wherein the cutting element is configured to move from a retracted position which allows transit of an end part of the working block. 8. The apparatus according to claim 1, wherein the basic block is provided within the mold during the dwell condition of the working block. 9. An apparatus for producing blocks of material for producing a building structure, the material being an expanded polystyrene, the apparatus comprising: a mold configured to form a working block including the material and a basic block of material, the basic block of material being formed adhered to a previously-formed block to form the working block, the mold including a forming chamber in which the working block and the basic block are formed, the forming chamber defined by a plurality of lateral walls and a rear wall, the forming chamber being open at a front thereof, in the forming chamber, the previously-formed block includes means for closing a front opening of the forming chamber during a dwell step of forming the basic block, the forming chamber receiving the material that is fed into the forming chamber and receiving a working fluid that is fed into the forming chamber to cause expansion and reciprocal adhesion of polystyrene spheres of the basic block and adhesion of the basic block to the previously-formed block, in order to form the basic block; anda cutting device configured to separate a predetermined block of material from the working block by cutting the predetermined block from the working block in a dwell condition in which the working block is partially disposed within the mold and partially extended from the mold, the cutting device comprising a supporting frame and a cutting element moving between a raised and retracted position and a lowered and forwarded position relative to the supporting frame to provide predetermined blocks having variable lengths,wherein the cutting device is longitudinally movable relative to the mold on a corresponding track or guide extending longitudinally parallel with a supporting surface for the working block to a respective longitudinal distance relative to the mold at which the predetermined blocks are cut to a predetermined length during the dwell step of forming the basic block, and the respective longitudinal distance of the cutting device from the mold being selectively modifiable to provide varying lengths of the predetermined blocks,wherein a movement of the cutting element is coincident with formation of the basic block of the material in the mold and adhesion of the basic block to the previously-formed block. 10. The apparatus according to claim 9, wherein the basic block is provided within the mold during the dwell condition of the working block. 11. The apparatus according to claim 1, wherein the dwell condition of the working block coincides with formation of the basic block of material in the mold and addition of the basic block to the working block. 12. The apparatus according to claim 8, wherein the dwell condition of the working block coincides with formation of the basic block of material in the mold and addition of the basic block to the working block.
