PROBLEM TO BE SOLVED: To provide a strip rubber continuous extrusion system by which an amount of discharge can be increased by increasing the number of rotations of a gear pump while temperature elevation is suppressed in the continuous extrusion molding of a strip rubber for molding a tire. SOLUTION: At least a first rubber continuous extrusion apparatus 1 and a second rubber continuous extrusion apparatus 2 are provided. The first rubber continuous extrusion apparatus 1 is provided with a first extruder 10 for kneading a fed rubber material and extruding it, a strainer 11 for removing foreign matters in the rubber material fed from the extruder 10, and a first molding die 12 for extruding and molding a strip rubber as a pre-process. The second rubber continuous extrusion apparatus 2 is provided with a second extruder 20 into which the strip rubber is fed as a pre-process and which kneads and extrudes it, and a gear pump 21 carrying the rubber material fed from the second extruder 20 to a second molding die 22. The strip rubber to be used for molding the tire is continuously extruded from the second molding die 22. COPYRIGHT: (C)2003,JPO |
