Claim 15:
16. A wrapping device for product wrappers comprising:
a winder comprising:
a gripper mechanically connected to one end of a tubular shaft, wherein said tubular shaft is rotatable about an approach axis (A) and translatable along said approach axis (A), and wherein said gripper is rotatable and translatable integrally with said tubular shaft;
an actuating rod, configured to act on said gripper, sliding along an actuating axis (B) parallel to, or coinciding with, said approach axis (A), wherein said actuating rod slides along said actuating axis (B) with respect to said tubular shaft and is rotationally constrained to said tubular shaft, and wherein said gripper is openable and closable in response to a translation of said actuating rod along said actuating axis (B);
a first electric motor operating on said actuating rod to translate said actuating rod along the actuating axis (B);
a second electric motor operating on said tubular shaft to translate said tubular shaft along the approach axis (A);

said device further comprising a control unit configured to drive the first electric motor and the second electric motor;
said device further comprising a third electric motor configured to rotate the tubular shaft and the actuating rod; said third electric motor being connected to a transmission shaft, wherein the transmission shaft extends between the winder and a further winder comprising a further gripper.
