<p>A winding and unwinding device (1), particularly for power and/or signal transmission cables, comprising a drum (2) that rotates about a main axis (3) around which a flexible transmission cable (4) is wound at least partially which has a first end (4a) that is associated with the drum and a second end (4b) that is arranged opposite the first end (4a) and is associable with a user device. Connection means (5) are associated with the first end (4a) for functional connection to means (105) for supplying power and/or signals. The connection means (5) comprise a connecting cable (6) that has a first terminal (6a), associated with the first end (4a), and a second terminal (6b), arranged opposite the first terminal (6a) and associable with the supply means (105). The connecting cable (6) is furthermore accommodated, at least partly, in a containment element (7) that is provided with a perimetric barrier wall (8) that is associated so as to rotate integrally with the drum (2) and with which the first terminal (6a) is associated, and with a central core (9) that is locked rotationally with respect to the drum and with which the second terminal (6b) is associated. The device (1) enables, during its rotation, the unwinding or winding of the transmission cable (4) on the drum (2) and either or both of the winding of the connecting cable (6) around the central core (9) and the unwinding of the connecting cable (6) toward the internal side of the barrier wall (8).</p> |
