Abstract

PURPOSE:To obtain an automobile tire superior in tire uniformity, by a method wherein a laminated member having a specific thickness is stuck to a cylindrical mold and joint end parts of the laminated member are joined to each other by joining pressure falling within a specific range by butting them with each other. CONSTITUTION:A textile ply 1 and inner linear 2 are laminated together beforehand, then a laminated member 3 is stuck to a cylindrical mold and joining end parts are joined to each other by butting them with each other by making use of a zipper 4 and molded. A thickness of the laminated member 3 and joining pressure further at the time of joining by butting them with each other are made respectively 2.0-6.0mm and 0.2-5.0kg/cm<2>. With this molding method, fixed rigidity can be given to the laminated member and also a joint area where the joint end parts are butted with each other is increased. Moreover, since the thickness of the laminated member and the pressure at the time of joining are made so as to fall within the optimum ranges, butt joining is performed under an adhesion state without generating creases in the vicinity of a joint. Then since even peeling of the joint is not generated in the molding process and further joining between the textile ply and inner liner can be fulfilled at a time, an improvement in productivity can be contrived.

する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of molding automobile tires for passenger cars, trucks, buses, etc., and particularly relates to an improvement in tire uniformity of radial tires using textile braai.

最近、このタイヤユニフォミティ−の不良に起因した走
行時の振動が重視されており、タイヤユニフォミティ−
の良好なタイヤが望まれている。"Prior art" Tire uniformity indicates the roundness of a tire with no uniformity of rigidity at the tire circumference -L.
Recently, attention has been paid to vibrations caused by poor tire uniformity during driving, and
A tire with good quality is desired.

れの部材について順次端部同士を重ね合わせて接合し成
型していた。Conventionally, in the case of a radial tire using textile ply, for example, an inner liner textile ply, a steel belt, etc. were sequentially attached to a cylindrical shape, and the ends of each member were successively overlapped and joined to form the tire.

こしていた。[Problems to be Solved by the Invention] However, in such a joining method, the thickness increases at the overlapped joint, resulting in a double textile cord, which locally increases the rigidity, so that the area around the tire circumference increases. Non-uniformity occurs, causing tire uniformity defects.

従来この解決方法として■重ね合わせ代を減少させる、

に至っていないのが実情である。Conventionally, the solution to this problem was to reduce the overlap,
- Various measures have been taken, such as uniformly dispersing the joints of each member so that they do not overlap, but the reality is that no fundamental solution has yet been reached.

れた自動車タイヤの成型方法を提供する点にある。An object of the present invention is to provide a method for molding an automobile tire that uses textile brazing and has excellent tire uniformity.

ルブライの端部同士を突合わせて接合する方法を採用し
ている。。[Means for solving the problem] By the way, in the case of radial tires for trucks and buses that have a steel braai structure, if the joints of the steel braais are overlapped and joined, the steel cord at the joint may break during driving, or the joint may break. To prevent the parts from peeling off, the conventional method has been to butt the ends of the steel braais together and join them. .

突合わせて接合する方法をとれば、タイヤユニフォミテ

して提供されていないのはかかる原因に基づく。However, in the case of textile braai, textile cords have lower rigidity than steel cords, and the braai itself is thinner, so if you simply butt the ends together like you would with steel braai, you will end up with wrinkles in the cord near the joint. etc., which is not desirable. This is the reason why this type of method has not been provided as a suitable method for textile brazing to date.

ある。Therefore, in this invention, tire uniformity can be improved by adopting a structure in which the textile ply is bonded to the inner liner in advance, and by setting the thickness of this bonding member and the pressure at the time of butt joining to an optimal range. This is what we have discovered.

すためタイヤユニフォミティ−が悪化する。As mentioned above, if only textiles or inner liners are used, the members are thin and have low rigidity, so wrinkles will occur if the joint ends are butted against each other. Even if the amount is less, the members are still thin and have low rigidity, so wrinkles will appear near the joints. If it exceeds 6.0■, it becomes difficult to apply bonding pressure to the center of the thickness direction of the butted end joint surfaces, resulting in poor adhesion of the joint, and the textile ply stretches during shaving during the vulcanization process, etc. This causes peeling of the joint. In addition, the joint ends are 0 and 2
Even when butt-joined with a welding pressure lower than kg/cd, adhesion is insufficient, and the textile braai is stretched during shaving during the vulcanization process, resulting in peeling of the joint. If the weight exceeds 5.0 kg/eJ and the tires are butt-joined, wrinkles will occur in the butt-butted portions, and the end scattering of the textile braai will occur, resulting in deterioration of tire uniformity.

される。[Function] Therefore, according to this molding method, Texta Ilbly is treated as a laminated member that has been laminated with the inner liner in advance, so it can have a certain degree of rigidity.
Moreover, the joint area to be butted also increases. Moreover, since the thickness of the laminated members and the pressure at the time of joining are set to the optimum range, the butt-joint can be performed in a close contact state without wrinkles occurring in the vicinity of the joint.

For those in which the thickness and bonding pressure of No. 3 are outside the optimum range of the present invention,
Molding was performed under the same conditions as in this example. Table 1 also shows the results.
