Abstract (en)
[origin: EP1748108A1] The auger has a hollow core (32) with an outer helical blade (34), and a movable cutter pin (42) taking an active position, where it projects outside the volume defined by the blade periphery, and a retracted position, where it is placed inside the volume. Displacement units displace the pin from retracted to active position. The displacement units have a dip tube (100), moving in translation and/or in rotation in the core, placed at the bottom end of the core. The movement of the tube relative to the bottom part of the core controls displacement of the pin from retracted to active position.
