ABSTRACT:
An apparatus and method is provided for fabricating plain-end pipe couplings. Ribbons of resin-soaked fiber reinforced plastic strands are wrapped about a rotating operably expandable mandrel which has placed therearound a pliable resilient form collar which defines an inner surface of such a coupling. After curing, the wrapped ribbons form a rigid coupling. The mandrel is thereafter collapsed and the coupling removed therefrom. The pliable collar is then separated from the coupling.
