- the clevis is released before the last cutting operation.
- This second operating mode makes it possible to move the yoke in masked time and thus reduce the time of a cutting cycle of the yoke 2b.
- step d) repeat step d) until the yoke 2b is reduced to pieces 2s by providing release of the yoke on the bearing surface 303 at least before cutting the last piece 2s.
- Figures 4 to 6 illustrate the operational phases described above concerning the establishment of the yoke 2b on the rotating members 210 according to the first operating mode.
- the yoke 2b which has an annular conformation with a substantially U-shaped section, is therefore arranged by means of the device 300 for placing in support (deployed) on the rotating members 210 of support so that a part of the outer surface (or yoke) is supported on these rotating members 210 support so as to define a single straight body having a substantially "U" section which extends longitudinally substantially in a direction orthogonal to the axis rotating bodies 210 support.
- the device 300 releases the yoke 2b.
