A method for belling the ends of thermoplastic pipes including the steps of delivering the pipes successively to an initial location adjacent conveyor means including a continuously driven endless belt, and transferring the pipes successively from the initial location onto the conveyor means in a spaced relationship with each pipe disposed for movement by the conveyor means in a direction transverse to the length of the pipe and in a spaced relationship through heating and belling stations.

Method for belling plastic pipe

Method and apparatus for belling an end of a length of thermoplastic pipe by thermally softening the end of the pipe, inserting an expansible belling head into the softened end, expanding the belling head to accomplish shaping of the thermoplastic material, cooling the pipe, and then separating the pipe from the belling head.
