An inplace gasket belling machine wherein a plastic pipe is received in a tilt clamp fixture and tilted thereon for receiving a heating bell on one end portion of the pipe. Heated fluid is directed over the inserted pipe end portion. The heating bell may be withdrawn from the pipe in intermittent steps to afford a temperature gradient along the pipe end portion. The pipe is then tilted to a horizontal disposition for the insertion of a gasket belling mandrel into the heated end portion of the pipe. A gasket magazine is supported adjacent the mandrel for automatically placing an annular gasket on the mandrel for insertion into the pipe end portion. The mandrel includes an outer housing and a mandrel body portion telescopically received within the outer housing. The outer housing has a stop shoulder and a gasket positioning sleeve extended forwardly therefrom. The mandrel body portion has a flared pipe expanding portion and a gasket carrying portion rearwardly thereof. Upon insertion of the flared portion into the heated end of the pipe, the outer housing collapses onto the mandrel body portion for precise positioning of the gasket within the pipe end portion. Upon withdrawal of the gasket positioning sleeve from said pipe end portion, the pipe end portion is collapsed by vacuum means onto the mandrel body portion and cooled prior to withdrawal of the mandrel body portion from the belled pipe end portion.

Inplace gasket belling machine

Apparatus for heating plastic pipe

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.
