The assembly applies an apex filler to the outer circumferential surface of an annular bead ring. The apex filler applying assembly incorporates an apex filler applicator that is preferably operable in conjunction with a plurality of server mechanisms. One server mechanism is a conveyor that receives a bead ring. A locator operates in conjunction with the conveyor to position the annular bead ring precisely on the conveyor so that it may be engaged by a transfer mechanism. The transfer mechanism removes the bead ring from the conveyor and mounts it on a chuck turret assembly. A chuck head in the chuck turret assembly engages the bead ring and accurately positions the bead ring relative to applying rollers in the apex filler applicator, in which position the apex filler--which has been directed from an extruder through an orienting mechanism, into an in-feed mechanism and severed to length by an in-flight guillotine cutter--is applied to the annular bead ring. After the apex filler has been applied to the bead ring the transfer mechanism removes the finished tire bead sub-assembly from the chuck head and deposits the tire bead sub-assembly on the conveyor for removal from the assembly.

[ We claim:] [1.] A method for applying an apex filler to an annular bead ring comprising the steps of:depositing an annular bead ring on a conveyor;indexing the conveyor to position the bead ring deposited thereon at a pick-up/delivery station;transferring the bead ring to a plurality of engaging means presented from a chuck head and positioned along a bolt circle of contracted diameter;said bolt circle being positioned within a radial plane common to all said engaging means;maintaining one of said engaging means fixedly positioned within said common radial plane;expanding the diameter of said bolt circle along which said engaging means are disposed to grasp the bead ring while continuing to maintain said one of said engaging means fixedly positioned within said common radial plane;positioning said bead ring in the nip of an apex applicator;feeding an elastomeric strip into said nip;applying said elastomeric strip to said annular bead ring;contracting the diameter of said bolt circle along which said engaging means are disposed to release said conjoined annular bead ring and apex filler; and,delivering said conjoined bead ring and apex filler to said pick-up/delivery station on said conveyor.
