ABSTRACT:
The disclosed embodiment of the present invention is an apparatus for bending plastic pipe so that it can be molded to a desired configuration. The disclosed apparatus includes a generally cylindrical container which is open at one end and contains a heat transfer medium, preferably in liquid form, in which the plastic pipe can be submerged. The container is mounted at an acute angle with respect to horizontal so that one end of a pipe can be inserted into the open end thereof. A heating unit maintains the heat transfer medium within the container at a regulated temperature which is within the temperature range for heating plastic pipe sufficiently to permit it to be molded. The container and heating unit are mounted on a carriage for providing portability to the apparatus.
