ABSTRACT:
The present invention relates to the continuous production of blocks of circular cross section of expanded cellular material. The material is deposited on a flexible liner which is movable sychronously with a flexible mold element through a stationary longitudinal shaping mold which is of circular cross sectional shape at its discharge end. In accordance with the present invention, cellular blocks of completely circular cross section are produced. The invention also provides for the heating of the flexible mold element to reduce the temperature difference between the elements contacting the expanded cellular material so that more uniform density is obtained.
