The double belt, or continuous press, is the more important machine in thermoinsulating panels production process.

Its function is to contrast the thrust of polyurethane foam during expansion phase; the pressing planes are composed of plates in electrowelded steel and worked on machine tools so as to guarantee a perfect flatness.

According to panel thickness and desired production speed double belts of different lengths are realized. The movement in height of upper belt is carried out by mechanic jacks, allowing the automatic adjustment of production thickness.

The lateral seal is guaranteed by a chain system of lateral containment, on which the side blocks are hooked.
