ABSTRACT:
A pipe coupling member for coupling together the ends of two pipes has a sleeve portion and a band member. The sleeve portion has an opening that extends between first and second ends. The band member is band shaped and is lcoated or embedded with the wall of the sleeve portion so as to be concentric therewith. The sleeve portion is made of a flexible elastomeric material and the band member is made of either fiber glass or polycarbonate plastic to provide reinforcement. The band member is stiff, yet resilient. The band member is confined to a central portion of the sleeve portion so that the first and second ends are flexible. The coupling member is manufactured using an annular mold. In the production process, the band member is supported and located within the central portion of the mold annulus by plural pins extending from the mold ends in a longitudinal direction. The annulus is then filled with elastomeric material. After molding, the pins are pulled out of the coupling member.
