- a hatch (not shown) may be provided on the casing 26, opposite the cylindrical part of section 30 of basket 18.
- the supply channel 34 and the means of advance order associated with it can also be movably mounted on the frame 10. A pivoting or sliding the channel then allows completely clear the basket 18. This can thus be replaced by another basket equipped with example of new or resharpened cutters and rules.
- the rotating basket 18 comprises, at the outside of the anvils 46, percussion irons 94 also oriented parallel to the axis of the basket.
- the number of percussion irons 94 is generally lower than that of anvils 46.
- a static basket 96 is interposed between the rotating basket and the casing 26 ( Figure 1) of the machine.
- This static basket 96 is fixed to the machine frame 10, near the irons of percussion 94. It essentially comprises a wall cylindrical which alternately includes, in the direction circumferential, 98 rasps and sizing zones 100.
- the rasps 98 are turned inwards and the calibration zones 100 are formed for example of grids or perforated plates, so as to form calibrated section passages.
- the inserts or chips 92 formed outside the anvils 46 are rotated by the irons of percussion 94 so as to be applied against graters 98 from the static basket 96.
- the fibers 102 thus formed pass through the calibration zones 100 when their section is small enough.
- the fragmented products collected in the well 14 of the machine are no longer pads or chips 92 as in the first mode embodiment described, but section fibers calibrated 102, which can in particular be used in the manufacture of particle board or paper.
- the invention is not limited to embodiments which have just been described in title of examples.
- the orientation of the axis of rotation 20 of the basket 18 as well as the number and orientation of supply channels 34 may be significantly different from those who have been described.
- a basket of horizontal axis but whose training in rotation is performed at its periphery, can be associated with two penetrating feed channels in the trash on either side of it and arranged substantially horizontally.
- the axis of rotation of the basket can be vertical.
- multiple channels inclined and descending feed can emerge simultaneously inside the basket.
