Abstract:
An inplace gasket belling machine for belling one end portion of a plastic pipe and inserting a gasket therein includes a preliminary mandrel and a primary mandrel. The preliminary mandrel has a pipe expanding portion disposed forwardly of a belling sleeve carrying portion whereby upon advancement of the preliminary mandrel, the belling sleeve is carried into the expanded pipe end portion. The primary mandrel has a gasket carrying portion and a gasket positioning sleeve slidable thereon whereby upon retraction of the preliminary mandrel from the belling sleeve and insertion of the primary mandrel therein, a gasket is positioned within the expanded pipe end portion. Upon retraction of the belling sleeve from the pipe end portion and retraction of the gasket positioning sleeve independently of the gasket carrying portion, the pipe end portion is collapsed onto the gasket carrying portion prior to retraction of the primary mandrel from the completed pipe end portion.
