PROBLEM TO BE SOLVED: To further improve the high productivity by a strip winding method by a method wherein a plurality of kinds of unvulcanized rubbers are tilled in one injection-molding machine in the order of extrusions, and from this injection-molding machine, the plurality of kinds of unvulcanized rubbers are continuously extruded in a strip-form on a forming drum, and are wound in order. SOLUTION: When an unvulcanized rubber (a) which is extruded last in the extrusion order is filled in the injection pot 1a of an injection-molding machine 1 from an extruder 2A, the injection-molding machine 1 advances as shown by arrow X1, and then, an unvulcanized rubber (b) which is extruded in front of it, is filled in the injection pot 1a from an extruder 2B. When the filling of the unvulcanized rubber (b) is completed, the injection-molding machine 1 advances as shown by arrow X2, and receives the filling of an unvulcanized rubber (c) which is first extruded from an extruder 2C. Then, the injection- molding machine 1 is moved to a location where it is confronted with a forming drum 3, and a rubber strip S which is extruded in order by the injection-molding machine 1 is continuously wound by a plurality of times on a tire intermediate molded article Z which is already formed on the forming drum 3. |
