とサイドウオールが結句けられる。The carcass cord 9 extends radially to both ends of the bead wire, and up to the layer of the radial tire in which the tire tread is reinforced with high rigidity, a cylindrical tire carcass is usually first prepared and the bead wire is wound around it. The carcass is then formed into a tire shape, at which stage the tread and sidewalls are tied together before being molded.

かる原因となる。It is known that the performance of pneumatic tires produced in this manner is highly dependent on how accurately the tire is applied to the top of the tire carcass. If incorrectly positioned, L.Red tires can cause irregular wear and the application of undesirable forces that can impede the handling of the vehicle equipped with the tire while driving.

。The wire, which is an important part of the bulging part, connects to the bead 9 holding part and is stretched in the axial direction by the expansion of the air bladder, and the tensioned wire supports the center of the bulging part precisely in the center between the bead holding parts. It becomes possible to inflate the bulge evenly and radially.

As a means of maintaining centering, an axially extending bundle of wires is stopped at a central connection point in the ring2, thereby adjusting the bulge of the periphery of the wire series and forming the distance between adjacent wires. Outside! Always keep constant against closing. This property maintains the cords at equal distances during the forming process of the radial tire carcass supported by the former. The former is first mounted on a suitable frame with a holding shaft and then mounted on the shaft together with other equipment (not shown) for externally placing the tire carcass on the former. A device (not shown) is also required to inflate the carcass so that the tread or tread and sidewalls can be placed on the carcass, and to hold the tread 9 or tread 9 and the site 8 wall on the carcass for about 1 m.

ールしながら例えば空気式に軸方向に移動する。The left and right bead holding parts are similar, and the structure of the bead holding part is illustrated in FIG. The bead holding section incorporates a component forming a cylindrical surface in the state before molding as shown in FIG. Form the semi-conical surface shown in Figure 6. Because of the semi-conical bulge of the part, the pawl moves axially, e.g. pneumatically, while controlling the bulge angle of the bead retainer in response to the tapered portion of the part.
ビード保持部は図５〜７で示されるタイヤカーカスの種

互いに近づいたり遠ざかったり軸方向え動く。The bead retainers are moved axially toward and away from each other in a conventional manner (not shown) to effectuate the various forming steps of the tire carcass shown in FIGS. 5-7.
ビード保持部にはコ゛ムリングがあり組込み部品の内側

留め金によって組込み部品に固定されている。Also, with this rubber ring, both ends of a series of wires that extend in the axial direction during the molding process are maintained at a ratio of 1:i3 between the left and right bead holders and are tied to the rubber ring, and are then fixed to the assembled parts using a clasp attached to the rubber ring. There is.

送り込まれる。The central bulge consists of a retaining plate fixed in an axially perpendicular position, on the outside of which there is a beaded rubber bladder as a removable retainer in the groove of the part. Air pressure is directed into the bladder through appropriate d-paths within the retaining plate assembly.

。A series of links connected at a central point in a grid (Figures 2-4)
A presser band is made by Adjacent links are connected so as to be in the open state 6 when fully opened, and in this way the lattice extends to a certain length in the circumferential direction. This allows the former to swell only up to a predetermined diameter.
押さえバンドの重要な機能はフォーマ−の成型過程でツ
イヤ−を等距離関係に保つことである。The important function of the holddown band is to keep the wheels in an equidistant relationship during the forming process of the former.

−の中心位置を保持している。The wire is secured to the pin with a suitable adhesive through a longitudinal hole in the head of the pin at the central point joining adjacent links. The wire is thus fixed to the pin and maintains the central position of the former.
中心穴はハト目でうめられている。The central hole is filled with eyelets.

が第７図の状態までふくらんでゆく間に空気は除々にカ
ーカスとトレッドの接着面から順次押し出されてゆく。Typically, annular tire treads are marked around a band of suitable retaining links placed exactly axially relative to the center of the former. Once positioned, the tire carcass and breaker can be assembled accurately. Since the initial contact is made only in a narrow central area, it is avoided that air remains between the carcass and the tread. This is an important feature of the former according to the invention. former
While the tire expands to the state shown in Figure 7, air is gradually pushed out from the bonding surface of the carcass and tread.
軸方向に伸びるワイヤーは中央の空気袋がふ（らむ（（
つれ引張られて初期過程ではワイヤーは空気袋の外周と
ビード保持部で実質的に直線匠なる。The wire that extends in the axial direction has an air bladder in the center.
During the initial process of being stretched, the wire forms a substantially straight line at the outer periphery of the air bladder and the bead holding area.

ふくらましも効果的にならないだろう。The wire is not as stretchable as the air bladder (usually made of rubber) or the outer rubber sleeve, so it effectively determines the shape of the former as it expands. Variations in the forces exerted on the tire material do not affect the forming result of the former.This is an important advantage of using an axially extending wire in conjunction with the central inflation bag; Initially, a conical shape is formed on both sides of the central part.As mentioned above for swelling the former central part: If there is no till, the wire does not necessarily need to be stretched from the bead holding part to the central part, and the former can also maintain the central position. Inflating outward will also not be effective.

ろう。At the final stage of the molding former, as shown in FIG. 7, the bead holding portion approaches and the air bag is inflated to the maximum allowable by the presser wire and band. The bladder rests on the fastener assembly, centrally located 4 and supported by an axially extending wire while being stabilized by a hold-down band. This could be done by conventional methods or by closing the gap, for example by providing an annular gap around the outer periphery of the air bladder that meets the inner edge of the pin that becomes the center point of the lattice link.

It has the role of holding the -゛ and also serving as a rotating shaft head. This partial rotational movement serves to hold the bead and swell radially, while pulling the carcass and maintaining tension as each holding device moves in the axial direction.

。The above molding former has the following advantages. Beat 9 of the carcass is firmly pressed down and the swelling only takes place in the center. The center line of the former does not deviate from the N1 center where the beads approach each other and swelling progresses. This allows the top of the carcass to be molded first.
The center of the tread is precisely arranged. This consistency is made possible by the former's use of a series of wires to hold the bladder in place during the molding process. And inflate the air bag with a presser pan l-
