There is disclosed a labelling machine (1) for applying at least one label (2) on an item (3; 3'), comprising :a spindle (22; 23) which can be fed with a flat label (2) cut from a band, and can rotate to determine the winding of the label (2) on the spindle (22; 23); a sealing element (26; 27) actuatable to weld opposite edges (48; 49) of the label (2) wound on the spindle (22; 23) so as to form a tubular element (4) having axis (D, D'); and a transfer element (28, 29) to apply the tubular element (4) the item (3, 3'); the transfer element (28, 29) is mobile forwards and backwards between a first position and a second position, in which it applies the tubular element (4) to the item (3, 3'); the transfer element (28, 29) comprises a wall (43) adapted to cooperate with a portion of an external side surface (60) of the tubular element (4) and an opening (44) connectable to a vacuum source (80), when the transfer element (28, 29) moves from the first position to the second position; the opening (44) is uncoupleable from the vacuum source (80) when the transfer element (28, 29) is in the second position. |
