An apparatus for reforming pipe ends by belling or the like. The apparatus includes a support structure which has a heater movably mounted thereon and is movable between a pipe end heating position and a second position remote from the heating position. A clamp is provided to hold the pipe in position during heating and forming. A forming mandrel is carried by power operated moving means which selectively moves the mandrel into forming engagement with an end portion of the pipe and after forming of the end portion the mandrel is retracted from engagement therewith. Cooling means are also provided to cool the formed pipe end portion.

A pipe end reforming apparatus comprising: a. a support; b. a mandrel; c. first means movably mounting said mandrel on said support with said mandrel being movable in a generally linear path between a retracted position and a forming position for engagement with an end portion of a pipe; d. clamp means mounted on said support and adapted for selectively holding a pipe in a preselected position; e. heating means; and f. second means movably mounting said heating means on said support with said heating means being movable, independently of said mandrel, in an arcuate path between a first position and a second position, When in said second position said heating means being in heat transfer relation to an end portion of a pipe and being in axial alignment with said clamp means and said mandrel and when in said first position said heating means being out of axial alignment with said mandrel and the pipe thereby providing clearance for said mandrel to move to the forming position whereby heating and forming can be accomplished without moving said pipe.
