Abstract (en)

[origin: EP0811751A1] The machine comprises a base (11) of a transfer trolley (12) which is mounted on a fixed guide (13). It is carried by a penetration trolley (14) which moves on this base. A cutting head (15) has an extension part (26) enabling displacement of the cutting head perpendicular to the displacement direction (D) of the penetration trolley. The head also has angulation components (27) enabling tipping of the head around its axis (A3) parallel to the displacement direction. The cutting head angulation components are positioned between the penetration trolley and the cutting head. The extension part comprises a runner (28), which is carried by the penetration trolley, and a slide (29) which engages the runner and carries the cutting head. It also has a control for displacement of the slide on the runner. The angulation components comprise jointly, an angulation shaft (32) rotating on the penetration trolley and carrying the runner and a control (33). A control (30) ensures displacement of the slide on the runner.
