Abstract: A multiple station plastic pipe belling machine in which an endless conveyor periodically receives one of a series of plastic pipes as each pipe is dumped from a V-trough receiving such pipes in sequence after their extrusion and cutting into predetermined pipe lengths, disposes the pipes so received parallel to, but spaced from, each other and advances the thus-disposed pipes in predetermined increments; positions the pipes in such a manner that their ends to be belled are first passed in such increments through a heater adjacent the edge of the endless conveyor, while the pipes are continuously rotated until each pipe passes out of the heater and is then carried in such increments by the endless conveyor into the first of a plurality of belling stations where a pair of semi-circular clamps encircle the pipe end and a mandrel or plug is inserted therein.
