Abstract (en)
The unwinding device preferably comprises three stations (13, 15, 17) for the rolls (BA, BB, BC); engaging members (21A, 21B) of the rolls in said stations; and in at least one of said two stations a lifting and lowering device (31, 33, 35) for the rolls. The lifting and lowering device comprises a pair of arms (51, 53) oscillating essentially synchronously and in opposite directions about respective fixed axes (51A, 53A), essentially parallel to the axis of the roll, and are each equipped with at least a contact member (73, 75) with the respective roll, oscillation of the arms causing lifting or lowering of the roll in contact with said members.
