1. 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;
wherein said winder comprises a first fork connected to a drive shaft of the first electric motor and constrained in translation along the actuating axis (B) to said actuating rod; said actuating rod being rotatable about said actuating axis (B) with respect to said first fork.
