Abstract

PURPOSE:To execute sure and close joining of butt joint section by heating each abutting edge part of a composite at a lower temperature than vulcanizing temperature in constituting a type carcass through butt joint of unvulcanized rubber and cord composite. CONSTITUTION:For example, one joint end face 8 and the other of a standard length sheet 2 are pressed each other according to an ordinary method after heating them from both upper and under surface sides before abutment of them through a heater plate 9. Or one joint end face 8 and the other are each other pressed by the heater plate 9 after abutment of them. By the process, whole plane of the joint end face 8 can be substantially subjected to tight adhesion, even if bloom occurs on the joint end faces 8 or in the case wherein a cord end edge is exposed. Temperature degree for heating must be lower than that for curing so that plasticity of unvulcanized rubber does not disappear.

Description of the Related Art When constructing a tire carcass, as is clear from FIG. 5, which schematically shows one example of the construction procedure, an unvulcanized rubber 12 is formed on the upper and lower surfaces of a cord 11 according to a conventional method. The unvulcanized rubber / cord composite long sheet 1 having a width of about 1 m obtained by coating is cut into a predetermined length sheet 2 on the cutting line a, and then the uniform length sheet 2 ... In order to form the carcass material 3, the steps of sequentially joining the standard length sheets 2 on the cutting surface 21 side thereof, and the length of one carcass constituent material 3 thus obtained, Tire molding drum 4 according to the molding procedure
A process of winding the endless shape on the upper part and joining the joints 5 is required.

肉厚にすることができる。As a joint means in the above-mentioned joint process, conventionally, a superposition method shown in FIG. 6 and a butting method shown in FIG. 7 are known, and the latter butting method is the former superposing method. It is possible to make the entire wall including the butt joint 7 have the same thickness without the occurrence of the thick wall 6 as seen in FIG.

(A) The joint portion 7 for plastic deformation of unvulcanized rubber
The pressing pressure between the joint end surfaces 8, 8 cannot be increased, and (b) the unvulcanized rubber has adhesiveness, but the degree of adhesion is rather weak. There is a problem that a defective adhesion portion is liable to occur between the No. 8 parts, and this tendency is particularly remarkable when there is a bloom (a crystal precipitation part of the rubber compounding agent) or the cord is exposed on the joining end surface 8.

In FIG. 1, the butt ends are the joint end faces 8 and 8 (FIG. 5). (Corresponding to the cutting surfaces 21 and 21 of FIG. 2), and in FIG. 2, after the joining end surfaces 8 and 8 are butted, the heater plates 9 and 9 are applied to heat from the upper and lower sides.

できる。The above-mentioned heating increases the adhesiveness of the unvulcanized rubber on the joint end faces 8 and 8. Therefore, in the joint method shown in FIG. 8 and 8 are pressed according to a common method, and in the joint method of FIG. 2, the heater plates 9 and 9 are pressed in the arrow direction to press the bonded end surfaces 8 and 8 together, so that the bonded end surfaces are temporarily Even in the case where bloom occurs in 8 or the edge of the cord is exposed, substantially the entire joint end surfaces 8 and 8 can be brought into close contact with each other.

略々均一に加熱できる。In the present invention, heating of the butt ends may be double-sided heating as shown in FIGS. 1 and 2, or single-sided heating as shown in FIG. Since the standard length sheet 2 and the carcass material 3 are usually thin and have a thickness of about 3 to 5 mm, the entire bonding end face 8 can be heated to a predetermined temperature substantially uniformly even with one-sided heating.

It is determined.

About 1 to 5 seconds is suitable. Since the thickness of the standard length sheet 2 and the carcass material 3 is about 3 to 5 mm and heat easily passes through, heating for a short time of about 0.1 to 5 seconds is sufficient.

After cutting the long sheet into a standard sheet as shown in FIG. 5, the standard sheet is joined in its cut surface by applying the butt joint method of the present invention and heating conditions (see Table 1). Three types of carcass materials having different values were obtained. Three types of tires 1, 2, and 3 of the present invention were manufactured by using the above three types of carcass materials according to a conventional method, and the incidence of convexity on the side portion was examined. The results are shown in Table 1. In the table, "ratio of occurrence rate of convexity" means that, except that the butt joint of the standard length sheet is not heated.
It is the ratio when the convexity of the side portion of the reference tire manufactured under exactly the same conditions as the present invention is set to "100".
