ABSTRACT:
A machine for removing a precut length of plastic pipe from an extrusion line, providing a bell on one end thereof, and providing a chamfer on the opposite end thereof. The pipe is received in a V-shaped trough along which it is longitudinally moved as it is delivered from the extruder. At predetermined intervals, a plurality of hydraulic pushers are actuated to move the pipe laterally from the trough onto a conveyor. The conveyor is indexed to a first position in which the axial location of the pipe is corrected and the end to be belled is heated. In a predetermined sequence of events, the conveyor is then indexed to a second position in which a belling plug is inserted into the heated end of the pipe; simultaneously, the opposite end of the pipe may be provided with an internal or external chamfer. When the conveyor is again indexed, the pipe is deposited onto a suitable system so that it may be conveyed to a shipping point.
