<p><P>PROBLEM TO BE SOLVED: To provide a bead set ring for a tire molding machine that can dispense with the post position correcting operation of a bead core by fully eliminating a risk of unexpected dislocation, falling-off, or the like of the bead core of specified dimensions fitted to a cylindrical protrusion of a ring-like member by a worker's manual work through the firm magnetic attraction of the bead core with holding permanent magnets, and fully preventing the bead core from being eccentrically fitted to the cylindrical protrusion. <P>SOLUTION: The bead set ring includes a cylindrical protrusion part 2 formed in ring shape as a whole to fittingly support the annular bead core stuck to the periphery of a tire component formed in cylindrical shape, and a flange portion 3 continuous with the outer peripheral side of the cylindrical protrusion part 2. A plurality of holding permanent magnets 4 magnetically attracting the bead core are disposed within an area that exceeds 90°measured from an optional position in a circumferential angle range. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
