Patent ID: 6994819

Claim:
In an apparatus comprising a housing having a pipe passage extending between each extremity of said housing, a pair of jaws having a generally symmetrical configuration with respect to each other disposed within said housing on opposite sides of said pipe passage, and a drive mechanism connected with respect to at least one of said jaws suitable for changing a distance between said jaws, a method for re-rounding flexible plastic pipe comprising the steps of: positioning said housing around an out-of-round flexible plastic pipe whereby said flexible pipe is disposed within said pipe passage and a major axis of said out-of-round flexible plastic pipe is substantially perpendicular to said jaws; compressing said out-of-round flexible plastic pipe by reducing said distance between said jaws until said major axis becomes a minor axis, forming a compressed flexible plastic pipe; and decompressing said compressed flexible plastic pipe by increasing said distance between said jaws, thereby allowing the compressed flexible plastic pipe to relax into a substantially round flexible plastic pipe.
