Zusammenfassung:	PROBLEM TO BE SOLVED: To fully demonstrate a function as a slim-high shape bead filler 34 and thereby raise the working efficiency. SOLUTION: A cylindrical filler sheet part 36 is molded outside of a molding drum (a carcass layer 18), hence no necessity to differentiate the stretching level of the filler sheet part 36 at a location in the axial direction and consequently, the positional precision of molding of the filler sheet part 36 is high. In addition, the main part 19 of the carcass layer 18 is deformed by bulging to get the filler sheet part 36 close to a filler main part 35, and thus, the filler sheet part 36 and the filler main part 35 can be closely superposed over each other to form a bead filler 34. On account of this molding procedure, no gap is generated between the filler sheet part 36 and the filler main part 35. COPYRIGHT: (C)2008,JPO&INPIT
