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.
Claims7
A method for making a plurality of fibrous strips and a ribbon of ligneous fibers comprising an assembly of the plurality of fibrous strips, wherein the ribbon has a calibrated thickness ranging between 0.1 mm and 1 mm, and equally an calibrated width ranging between 2 mm and 10 mm, comprising the steps of:
- cutting ligneous logs or canes into square-edged planks, each having a predefined length;
- and
- separating the plurality of strips from a surface of one of the square-edged planks by an orthogonal cutting process with a depth of cut substantially equal to the thickness of each of the plurality of strips, wherein cutting is parallel to the fibers of the square-edged plank, and wherein the width of the plurality of the strips is more than 1 mm;
- aligning the plurality of the strips according to their fiber direction;
- assembling the plurality of the strips to make the ribbon;
- winding the ribbon into a reel;
- and
- weaving the wound ribbon to make a reinforcing fabric.
