<p>A method and apparatus for separating a cut end (5) from a tubular element (T), such as a cast iron pipe. The element (T) is horizontal and placed on means (1) for supporting and driving it in rotation around its axis (X-X) with axial immobilization. A separator roller (E) is rotatably mounted around an axis (Y-Y) parallel to the axis (X-X) on a yoke (13) supported by a jack (16) enabling the roller to advance towards the axis (X-X) in a radial direction. The roller comprises an annular central wedge (8) bordered by two lateral cylinders (10a, 10b), and penetrates during the cutting operation into a groove (3) made by the cutting tool (2) in the wall of the element (T). At the end of the cutting operation the wedge laterally separates the cut end away from the cutting tool, to thereby avoid damaging the tool.</p> |
