Abstract
An unwinder (1) of rolls (B1, B2) including a bearing structure (3) and two pairs of arms (11A, 11B; 13A, 13B) supported movable on the bearing structure (3). The unwinder further includes a splicing machine (31). The bearing structure (3) includes a base (5) and an upright (7) extending from the base, on which a cross member (33) is supported. The cross member (33) includes an intermediate portion (33A) rigidly bound to the upright (7) and a pair of lateral supports (33B, 33C) adapted to assume at least one operating position and one non-operating position, with respect to the inter-mediate portion (33A) of the cross member (33).
