The needle writing head comprises a support in two parts (5 and 6), each comprising recesses (15, or 18) forming guide paths for needles (16) located along two rows. The part (6) is movable parallel to the row of needles (16) over a distance equal to one-half of the distance between centers of the needles (16) so as to make it possible to place the needles of the second row in alignment or staggered in relation to the needles of the first row. Means (19 to 26) consist of notching means to fix the two relative positions of the parts (5 and 6). The latter (5 and 6) are rubies and the part (5) is in two parts (12and 13) glued at (14).
