METHOD FOR MANUFACTURING PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To lower the tread break-off during unloading a tire after vulcanizing with a single split vulcanization mold. SOLUTION: This method for manufacturing a pneumatic tire uses the single split mold and vulcanization-molds the tire by covering the surface of a tread rubber composition composed of 65 pts.wt. or below of a filler loadings to 100 pts.wt. of a diene rubber with an unvulcanized belt-like sheet as a rubber composition which is composed of 65 pts.wt. or more of a filler to 100 pts.wt. of the diene rubber and has a thickness of 0.5 to 4.0 mm and a breaking strength (TB) after vulcanization of 20 to 100 MPa. Preferably the width of the unvulcanized belt-like sheet is equivalent to 60% or less and its breaking strength (TB) after vulcanization is 22 to 50 MPa. COPYRIGHT: (C)2004,JPO&NCIPI
