RE-SPOOLING UNIT FOR A MACHINE USED TO TREAT STRIP MATERIAL

摘要

The re-winding unit comprises a frame (1), a re-winding shaft (2) rotated by shaft actuation means and around which a web material (M) is wound to form a spool (B), said re-winding shaft (2) being displaced radially along guide means (3) as the diameter of said spool (B) increases, and a pressure roller (4) that presses against the spool (B) being formed on the re-winding shaft (2). The pressure roller (4) is installed in a fixed position on the frame (1) and displacement actuation means or contrast means perform or allow a radial movement of the re-winding shaft (2) while at the same time maintaining a pre-established winding pressure between the spool (B) being formed on the re-winding shaft (2) and the pressure roller (4).
