发明名称 GREEN-TIRE MOLDING APPARATUS AND METHOD OF TIRE MANUFACTURE
摘要 <P>PROBLEM TO BE SOLVED: To provide a green-tire molding apparatus preventing defects in manufacture of a pneumatic tire when a second construction member at least including a tread rubber sheet is pasted to a green case 11; and a method for manufacturing a tire by using the green-tire molding apparatus. Ž<P>SOLUTION: This green-tire molding apparatus 100 comprises a molding roll 200 for molding the green case 11 by expanding a first construction member into the shape of the green tire, while pasting the second construction member 12 onto the green case 11; and a pressing roller 300 for pressing the second construction member 12. The molding roll 200 comprises a pressing part 210 for pressing inner side surface 20 of the green case 11 outward from the inner side surface 20; and an expansion/contraction part 220 for expanding/contracting the pressing part 210 along the tire-diameter direction. The pressing part 210 has a pressing surface 210A for pressing the inner side surface 20. The pressing surface 210A presses the inner side surface 20 when expanded outward in the tire diameter direction by the expansion/contraction part 220. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
