【０００２】
【従来の技術】従来、極性がほぼ等しい加硫ゴム同士を
接着するには、加硫ゴムの被接着面をバフ加工して凹凸

【０００３】ところで、ゴムの接着に当り、接着される
ゴムの極性が互いに大きく異なると、接着されるゴム同

【０００４】即ち、互いに極性の異なる加硫ゴム同士を
接着する場合は、一方の加硫ゴムの被接着面に、接着さ

シートを貼り合わせて加硫し、この中間ゴム層の表面を
バフ加工して凹凸付けし、この面にゴム糊を塗布した
後、未加硫ゴムの接着用シートを介して他方の加硫ゴム
を当接し、熱プレスで加熱加圧する。
【０００５】また、互いに極性の異なる加硫ゴムと未加

【０００７】しかし、中間ゴム層を形成する加硫ゴムの
被接着面が平坦面ではなく、凹凸のある複雑異形形状で
ある場合、前記中間ゴムシートが薄いと、加硫時に中間
ゴムシートが流動して被接着面の凹部にたまり、凸部に
中間ゴム層が形成されなくなったり中間ゴム層が極端に
薄くなったりして、この部分で十分な接着が行われない
場合がある。
【０００８】また、この中間ゴム層は、バフ加工して凹
凸付けするため、バフ加工を行っても中間ゴム層が完全
に除去されない程度の厚さであることが必要とされる。
【０００９】このようなことから、中間ゴム層は、ある
程度の厚さを有することが必要となり、薄層化にも限界
があった。
【００１０】本発明は上記従来の問題点を解決し、互い
に極性の異なる加硫ゴム同士又は加硫ゴムと未加硫ゴム

【００１２】本発明においては、未加硫ゴムを付着させ
た織布を用いるため、中間ゴム層を形成する第１のゴム
の被接着面が凹凸のある複雑異形形状であっても、織布
により加硫時のゴムの流動が阻止され、被接着面全体に
わたって均一な中間ゴム層を確実に形成することができ

【００１３】しかも、加硫後織布を剥離することで、こ
の中間ゴム層に織布の剥離跡の凹凸を付与することがで
きるので、バフ加工は不要となる。
【００１４】このように、加硫時の中間ゴムの流動の問

に際し、引張力で容易に切断しない程度の十分な強度を
有し、かつ、剥離後、中間ゴム層に良好な凹凸が付与さ
れる程度の目開きを有するものであれば良く、特に制限
はない。一般的には、十分な引張強度と耐熱性を有し、
適度な目開きを有し、しかも、比較的安価にかつ容易に
