The device (1) comprises a feeding path (P) of the rolls ( R, R1) to be closed and a closing station placed along that path. The closing station of the tail end comprises two rollers (15, 17) forming a cradle (19) for receiving the rolls (R, R1) and a closing member (21) of the tail end (L). The device also comprises a rotating assembly (23) that rotates around an axis (A- A) transverse respect to the feeding path of the rolls and comprising groups (27A, 27B, 27C) of arms (28A; 28B, 28C) arranged with respect to one another angularly displaced around the rotation axis of the rotating assembly (23). Each arm comprises a front part (29) configured to eject a roll ( R, R1 ) from the cradle (19) and a back part (31) configured to hold subsequent rolls along the feeding path, preventing their entering in the closing station until the ejection of the roll from the cradle (19). The rotation of one step of the rotating assembly (23) causes the ejection of a closed roll (R) from the cradle (19) and allows the entering in said cradle (19) of a subsequent roll (R1) to be closed. |
