Summary: | PROBLEM TO BE SOLVED: To obtain a hollow extrusion molding of a desired shape without incurring the expansion of an installation space and the deterioration of productivity. SOLUTION: This manufacturing device for a hollow extrusion molding is made up of an inner layer extrusion molding head 10 for extrusion-molding an inner layer (x) of a rubber material and an intermediate layer extrusion- molding head 20 for extrusion-molding an intermediate layer (y) of a synthetic resin material, formed in a single piece together with an insulating material 40 interposed in between. The intermediate layer (y) is extrusion-molded from the intermediate layer extrusion-molding head 20 directly onto the outer surface of the inner layer (x) extrusion-molded from the inner layer extrusion-molding head 10. |
