Abstract
The present invention provides a method and apparatus for forming an apex filler (13). The invention also provides a method and apparatus that is uniquely adapted for applying an apex filler (13) onto a bead ring sub-assembly (14) without the introduction of stresses at the outer edge (50) of the apex filler (13). The apex filler forming apparatus (10) works in conjunction with an extruder (43) which presents a linear strip (42) of elastomeric material having a pre-determined cross-section. A pair of opposed, forming rollers (33) present a nip (35) therebetween. Means (36) are provided to rotate the rollers (33). Rotation of the forming rollers (33) causes the nip (35) frictionally to engage the elastomeric strip (42). The interaction between the elastomeric strip (42) and the nip (35) effects rotary motion of the elastomeric strip (42) and increases the circumferential length of the elastomeric strip (42) proportionally to the radial distance outwardly from the base (49) thereof. The apex forming mechanism (10) is operative in conjunction with an apex filler applying apparatus (11) to apply the apex filler (13) formed from the elastomeric strip (42) onto the radially outer surface (46) of a bead ring sub-assembly (14). Mounting chucks (21) are provided to position and rotatably support the bead ring sub-assembly (14) while the apex filler (13) is applied thereto.
