Abstract
A method for making a fibrous strip configured for making a ribbon with a thickness ranging between 0.1 mm and 1 mm and a width ranging between 2 mm and 10 mm. The ligneous logs or cans are cut into square-edged plank with a predefined length. The strip is separated from a surface of the square-edged plank by an orthogonal cutting process. The depth of cut is equal to the thickness of the strip. The cutting speed direction is parallel to the fibers of the square-edged plank. Also, a fibrous reinforcement is obtained using the method and a device for implements the method.

1-16. (canceled)
A ribbon of ligneous fibers, comprising an assembly of strips of fibers with a calibrated thickness ranging between 0.1 mm and 1 mm, and an equally calibrated width ranging between 2 mm and 10 mm;
- wherein length, density and direction of the strips are calibrated, and the strips are extracted using a cutting process that comprises a displacement of a cutting edge parallel to a fiber direction.
