ABSTRACT:
According to the present invention, a bead assembly consisting of a combination of a ring shaped bead core, a bead filler and a flipper is manufactured by continuous automated steps, whereby productivity is greatly improved. The present invention is characterized by the steps of providing bead locking drums on the free end portions of a plurality of rotary arms arranged radially around the center of rotation thereof, and turning and stopping these rotary arms sequentially so as to set a bead core on a bead locking drum stopped in a first stopping position A, wind a bead filler around the bead core set on the bead locking drum stopped in a second stopping position B to form a bead assembly, and then take out the bead assembly formed on the bead locking drum stopped in a final stopping position D. A third stopping position C is set between the second and final stopping positions, and a flipper is pasted on the bead assembly stopped in this stopping position C.
