    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.

    Abstract translation: 本发明提供一种用于形成顶点填充物（13）的方法和装置。 本发明还提供一种独特地适用于在胎圈环子组件（14）上施加顶点填料（13）而不在顶部填料（13）的外边缘（50）处引入应力的方法和装置。 顶部填充剂形成装置（10）与挤出机（43）一起工作，该挤出机提供具有预定横截面的弹性材料的线性条（42）。 一对相对的成形辊（33）在其间形成有辊隙（35）。 提供装置（36）以使辊（33）旋转。 成形辊（33）的旋转导致辊隙（35）摩擦地接合弹性体带（42）。 弹性条（42）和辊隙（35）之间的相互作用影响弹性条（42）的旋转运动，并且将弹性体条（42）的周向长度与其基部（49）向外的径向距离成比例地增加 。 顶点形成机构（10）与顶部填充剂施加装置（11）结合操作，以将由弹性体条（42）形成的顶点填充物（13）施加到胎圈环子带的径向外表面（46）上， 组件（14）。 提供安装卡盘（21）以便在将顶点填充物（13）施加到其上时定位和可旋转地支撑胎圈环子组件（14）。

    Abstract: A tire includes: a tire frame member formed in a ring shape from a frame resin material, and including a pair of bead sections, a pair of side sections, and a crown section; a ring shaped bead core that is embedded in and joined to each of the bead sections, and that is formed by a single strand, or plurality of strands, of bead cord extending in the tire circumferential direction, and covered with, and joined to, a covering resin material; and an extension portion that extends from each of the bead cores in a direction that intersects with the tire circumferential direction when viewed from a tire side face, and that is joined to the tire frame member.

    Abstract: Strands of steel bead wire or the like are individually surrounded with rubber and the rubber is then partially cured sufficiently by irradiation so that the rubber remains moldably plastic and the final cure will completely cure the rubber. Each bead core when completed is often enclosed in fabric. The completed bead assembly is incorporated in the carcass of a tire. When the tires, including the carcass, tread, etc., are cured, the rubber in the beads is completely cured and the beads are securely bonded to the balance of the tire.
