The invention relates to a re-spooling unit comprising : a frame (1); a re-spooling arbor (2) rotated by arbor actuation means and around which a strip material (M) is wound in order to form a spool (B), said re-spooling arbor (2) being moved radially along guiding means (3) as the diameter of the spool (B) increases; and a pressure roller (4) that presses against the spool (B) being formed on the re-spooling arbor (2). The pressure roller (4) is installed in a fixed position on the frame (1) and movement actuation means or contrast means perform or allow the radial movement of the re-spooling arbor (2) while maintaining a pre-established spooling pressure between the spool (B) being formed on the re-spooling arbor (2) and the pressure roller (4).
