There is described a labelling unit (15) comprising support means (20) and a receiving member (21) adapted to carry an article (3) to be labeled as well as to receive a label (2), and supported by the support means (20) in a translational and rotational manner with respect to an axis (F); the receiving member (21) is movable along the axis (F) between a raised position, in which it axially protrudes from the support means (20) and is adapted to receive the article (3) on its top portion (22) and the label (2) wrapped around its lateral wall (23), and a retracted position, in which it is housed within the support means (20) so as to permit insertion of the article (3) into the label (2) welded in an endless configuration; the lateral wall (23) of the receiving member (21) comprises first suction means (41) cooperating in use with a leading edge (45) of the label (2), and second suction means (39, 42, 40) cooperating in use with a remaining part (46, 47, 48) of the label (2); during wrapping of the label (2) around the receiving member (21), the first suction means (41) are activated prior to the second suction means (39, 42, 40) to maximize the retention force on the leading edge (45) of the label (2) at the beginning of the transfer of the latter onto the receiving member (21). |
