縁領載に並設する。Therefore, when arranging both breaker layers symmetrically, it is important to form the upper breaker layer wider than the lower breaker layer so that it protrudes from the side of the lower breaker layer (3). ” The protruding free edge area of the three-way breaker layer is utilized for cross-bond formation. For the purpose of fabrication, fabrics are made from heat-shrinkable materials (e.g. polyester, polyamide), in which the strips are placed side by side on the edges of the fabric.
こうしてブレーカ縁部に作られた交差結合はタイヤの走
行時に所要の弾性変形を可能にする。The cross-bond thus created at the breaker edge allows the required elastic deformation when the tire is running.

It is particularly preferable to include
