1. Apparatus (1) for winding at least one strip (2, 3) of material for the production of electrical energy storage devices, the apparatus (1) comprising:
a winding core (5) rotatable around a rotation axis (R), configured to grip said strip (2, 3) and actuatable to carry in rotation the gripped strip (2, 3) and thus form a winding (4) about the rotation axis (R) from a predetermined-length portion of said strip (2, 3);
a feed unit (6, 7, 8) to feed the strip (2, 3) of material to the winding core (5); and
a handling device (20) configured to move the winding core (5) at least between a winding station (A), at which the winding core (5) is configured to receive the strip (2, 3) in feeding, grip it and wind it about the rotation axis (R), and a second station (B, C), at which the apparatus (1) is configured to perform on the formed winding (4) a further process successive to the winding of the strip;
wherein the handling device (20) is configured to move the winding core (5) from the winding station (A) to the second station (B, C) during the winding about the core (5) of at least part of said predetermined-length portion;
the apparatus comprising a fixed frame (13), wherein the feed unit (6, 7, 8) is mounted to the frame (13) in a movable manner;
and wherein the apparatus further comprises an actuator configured to drive a movement of the feed unit (6, 7, 8) relative to the frame (13), during the movement of the winding core (5) from the winding station (A) to the second station (B, C), in order to adjust the positioning of the strip (2, 3) in feeding to the core (5) according to a trajectory (T) of this latter between the winding station (A) and the second station (B, C).
