An apparatus (10) for unwinding wire from reels with high inertia, comprising, on a frame (11) that surrounds a fixed supporting base (12) for a reel (13), an unwinding assembly (14) that is connected to a wire tension compensation assembly (15), which is in turn associated with elastic contrast means (17), the unwinding assembly (14) comprising at least one arm (18) that is rotatably associated with the frame (11) with a rotation axis that is parallel to the unwinding axis of the reel (13), and on which guiding elements are pivoted which are suitable to form an exit path for the wire (16) toward the feed after passing through the compensation assembly (15), the compensation assembly comprising at least one first pulley (19) that is translationally fixed with respect to the frame (11) and a second pulley (20) that is translationally movable with respect to the first pulley (19), the pulleys (19,20) forming as a whole a multiple hoist structure, the second pulley (20) being associated with the elastic contrast means (17). <IMAGE> |
