Continuous fibrous tape comprising fibres and method for making such tape

A continuous fibrous tape, comprising a substantially planar sheet of natural fibres of length Li, said sheet having a longitudinal dimension L, a transverse dimension w;

• said sheet comprising substantially planar units positioned in n longitudinal lines, with n being an integer of at least 4, said longitudinal lines being positioned next to each other, each planar unit comprising individual natural fibres having substantially the same length Li;
• each planar unit having a longitudinal dimension Li and a transverse dimension w/n, each planar unit having a first and a second transverse peripheral edge, opposite to each other and a first and a second longitudinal peripheral edge, opposite to each other;
• said first and said second transverse peripheral edge having a dimension w/n and said first and said second longitudinal peripheral edge having a dimension Li,
• each longitudinal line comprising a plurality of planar units positioned in such a way that the first transverse peripheral edge of a first planar unit is adjoining the second transverse peripheral edge of a second planar unit adjoining said first planar unit,
• wherein the transverse peripheral edges of planar units in a longitudinal line are misaligned in longitudinal direction with the transverse peripheral edges of planar units in an adjoining longitudinal line by a misalignment distance Lv, wherein the misalignment distance Lv is at least 3 w/n;
• and wherein, if the misalignment distance Lv between the transverse peripheral edge of planar units in a first longitudinal line and the transverse peripheral edges of planar units in a second longitudinal line is less than 3 w/n, then there are at least two longitudinal lines positioned between the first longitudinal line and the second longitudinal line.
