ABSTRACT:
A molding device for manufacturing a multiple layer product includes an extruder for extruding material to be molded, a blow head for receiving the material from the extruders and for supplying the material to a mold, and a passage connected with the extruder and divided into a plurality of branch passages connected with the blow head. An accumulator is provided on each of the branch passages, and a detector is provided in the accumulator for detecting the quantity of material introduced into the accumulator. A lock device locks the accumulator when the quantity of the material detected by the detector reaches a predetermined value, As a result a homogeneous layer can be obtained across the product.
