Since a sealing member is provided at the one end of each endless belt, the sealing member seals the gap between the endless belts, and the foaming pressure in the molding passage also causes the formation of the molded body. It is possible to prevent burr from flowing out from the gap between the endless belts. Also, by disposing this sealing member, the gap between the endless belts can be sealed as described above, so the design criteria for the gap of the endless belt can be relaxed, and equipment design becomes easier, and equipment cost is reduced. Will be cheaper.
