The machine also comprises a safety device (20) to inhibit discharge of the residual trunk resulting from cutting the last piece until the swinging structure (7) is brought to the receded position. The displacement of the swinging structure (7) may be provided by a lever (13) operable to positively provide advancement and return thereof both quick and slow to the receded position.</p> |
