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.] Apparatus for applying an apex filler to an annular bead ring comprising:chuck means for selectively receiving an annular bead ring having an outer circumferential surface;a pair of opposed, frusto-conical, applying rollers each having a rotational axis and outer surfaces, portions of which are spaced, one with respect to the other, in order to define a nip therebetween having a cross sectional configuration in the shape of the desired apex filler;means for delivering said chuck means, at least when supporting an annular bead ring, into said nip;means for presenting a linear strip of uncured elastomeric material in the general cross sectional configuration of the desired apex filler to the outer circumferential surface of said annular bead ring;said nip adapted to engage said linear strip of uncured elastomeric material and to apply said linear strip to said outer circumferential surface of said annular bead ring;means for cutting said elastomeric strip to the length required to cover said outer circumferential surface of said annular bead ring; andretainers to engage substantially the entire apex filler as it is applied to said outer circumferential surface of said bead ring in order substantially to maintain the radial disposition in which said apex filler is applied to said bead ring by said nip while obviating adherence between said retainers and said elastomeric strip.
