Abstract
In a bead manufacturing method and bead manufacturing device, a former rotatably supported on a support base and pivotably holds opposite end portions of a plurality of elastically deformable spring members arranged on an outer circumference thereof with gaps in a circumferential direction for annularly winding a bead filler around the spring members, an actuation mechanism is provided for curving the spring members in the radial directions of the former, and a bead core holding portion is arranged at one end side of the former for holding a bead core. When the spring members are elastically deformed outward in the radial directions of the former to a semicircular shape, the bead filler annularly wound around the spring members are raised up to fixedly fit a short bottom side thereof on the outer circumference of the bead core held at one end side of the former.
