COUPLING WITH EXTENDING PARTING LINE
First Claim
1. A method of manufacturing a coupling segment comprising:
- obtaining a mold having an interior and an exterior, the interior defining an interior surface, the interior surface defining a cavity, the cavity including a border line at an outermost edge of the cavity;
placing a material in liquid form into the cavity in the mold; and
removing a coupling segment from the mold, the coupling segment formed from the material, the coupling segment including an outer surface, an inner surface, a first end, a second end, a first fastener pad protruding proximate to the first end, a second fastener pad protruding proximate to the second end, and a parting line extending along the border line of the cavity of the mold prior to removal of the coupling segment from the mold, the parting line offset from a top surface of each fastener pad.
