ABSTRACT:
A splicing unit for integrally joining ends of seal strip material to form a continuous annular seal ring comprises two reinforced elastomeric ply strips with an unreinforced elastomeric gum interposed between them to form an H-section configuration, the length of the unit being substantially the width of the seal strip while the thickness of the gum between the ply strips is substantially the thickness of the seal material to be joined. The ends of the seal strip are inserted between the legs of the H-section on either side of the unreinforced gum and cured to form the integrally spliced seal ring.
