Abstract
A machine for use in butt fusing in axial alignment plastic pipe having a selected maximum diameter is adaptable by the use of specially designed inserts secured in the lower portions of fixed and moveable clamps, the inserts serving to elevationally raise segments of pipes to be joined when the machine is used to manufacture a segmented pipe turn. In addition to the employment of inserts providing increased height of support for pipe segments, the pivotal upper portions for the fixed and moveable clamps are replaced by specially designed upper clamp portions that have contacting surfaces configured to accept inclined and elevationally upwardly supported pipe segments. By the use of such specially designed inserts and replacement upper clamp portions a butt fusion machine can be employed to manufacture segmented pipe turns of the maximum pipe diameter for which the machine is designed.
