Each cut assembly has a cutter-bar (7), a cutting blade (8) and a deflector (9). Elastic maintaining units (10) i.e. push button, maintain each cut assembly in one of the notch of the tool support. The maintaining units are arranged between a lateral sidewall (5) of the notches and one of the cut assemblies, and take back the cut assembly in a separated position of the sidewall of the notch of the tool support.</p> |
