性を低下させることを意図したものではない。2. Description of the Related Art In general, a steel cord is used as a reinforcing material of a tire. However, since the rigidity of the steel cord is different from that of rubber, in the case of a tire formed by laminating reinforcing layers, a reinforcing layer (steel layer) is used. (Between the layers of embedded cord). Further, since rubber is easily oriented in the processing direction (plane), when a crack is generated due to a strain perpendicular to the processing surface, the rubber is more likely to be broken. The members covering these steel cords are processed in a rolling process, etc., but in general,
Since the structure of the tire is formed by laminating this sheet-like thing, the destruction between the reinforcing layers is affected by the orientation of the rubber,
There has been a problem that a destruction in the direction parallel to the lamination surface is caused. In consideration of such orientation of the rubber layer, there has been developed a rubber product in which a large number of thin rubber layers are laminated and a direction perpendicular to each layer is used as a surface portion (Japanese Patent Application Laid-Open No. H9-1990). This is not intended to reduce the orientation of the rubber layer itself.
