ABSTRACT:
The present invention relates to an apparatus for economically molding extruded products containing reinforcement in desired shapes and in large quantities. The operation of the apparatus comprises inserting a reinforcement such as reinforcing bars into extruding materials such as cement, gypsum, plastics or the like during the extrusion molding stage and encasing them under pressure in a body in order to produce extruded articles containing reinforcement which are most suitable for use as construction or structural materials having high rigidity and which are light in weight. Moreover, the above-mentioned extrusion molding can be performed no matter how complicated the shape and structure of the reinforcement may be.
