ABSTRACT:
A process and apparatus for minimizing breakage and stretching during the high speed production of plastic pipe is provided wherein a pipe is extruded at a first linear rate of speed, a slack segment is established and maintained between the extruder and a pipe winder, and the pipe is taken up on the winder at a second linear rate of speed which is the same as or different from the first rate, wherein the pipe is taken up on the winder responsive to the degree of slack in the slack segment.
