    摘要: The machine comprises an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (Na, Nb), and at least one unwinding station (15). A winding device (41, 53) is arranged in the unwinding station, and a longitudinal strip (S) of web material is fed to it and a respective spool (B) of web material is formed in it. A control unit (70) is also provided, configured to control the winding speed of the longitudinal strip (S) in the winding station (15), so as to perform an acceleration cycle to accelerate the winding of the longitudinal strip (S), comprising at least one step of gradually increasing the feeding speed (Vp) of the longitudinal strip (S), wherein the feeding speed is linked to the diameter of the spool (B).

    摘要: An unwinder of reels of web material wound around winding spindles (A), includes a unwinding station (13) with at least one unwinding member (23) to rotate a reel (B) that is located in the unwinding station and feed the web material toward a delivery path (E). Lifting members (51, 53) are provided to lift a spindle of a first exhausted reel from the unwinding station (13), in a removal position (PR). An insertion member (7; 33) is further provided to insert a second reel into the unwinding station (13). A pressing member (61) is arranged to press the web material coming from the first reel in removal position (PR) against the second reel in the unwinding station (13).
