Abstract
Apparatus for externally and internally peeling pipes includes a drill head secured to one end of an elongated drill rod and an external cutter head longitudinally-spaced from the drill head in the direction of movement of a pipe through the apparatus. A feed mechanism is positioned adjacent the drill head for feeding a pipe completely past the drill head and at least partially through the external cutter head. An extraction feed mechanism is positioned on the opposite side of the external cutter head from the drill head for pulling pipes completely past the external cutter head. The feed mechanism adjacent the drill head includes opposed pairs of rollers, one pair of which is radially aligned with the cutters on the drill head.
