ABSTRACT:
A mandrel device which guides the end of a pipe or tube to a position outwardly of the path of an expander body, with a camming mechanism to force the expander body from an inward position to an outward position, and holding that outward position so as to achieve the desired gasket-receiving enlargement of the tubular work object. In a subsequent stage, another camming feature forces the expander body radially inwardly, to permit the tubular work object, now carrying the sealing ring in a position which would mean interference by the expander body, to be released over the end of the mandrel. The two camming components are carried by sub-assemblies axially movable with respect to stationary parts of the mandrel; and they are interrelated to have both movement together and movement with respect to one another, achieving the outward and inward camming effects in a plural-stage motion sequence and nature.
