| (54) | LABELLING APPARATUS AND METHOD |
| (57) A labelling apparatus (1) comprises: a feed roller (11); a gluing roller (12); a
cutting roller (13), provided with a knife (130), and a transfer carousel (14), including
a plurality of suction protrusion arrangements (140), angularly distributed along
a periphery of the transfer carousel (14) and provided with corresponding recesses
(140R). The transfer carousel (14) is adapted to receive a web (2) from the feed roller
(11) in a loading zone (C), to keep the web (2) adherent to one or more of the suction
protrusion arrangements (140) and to bring the labels (20) into contact with corresponding
bottles (21), in an unloading zone (S). The transfer carousel (14) is also configured
for interacting with the gluing roller (12) in a gluing zone (I) and with the cutting
roller (13) in a cutting zone (T), where the rotations of the gluing roller (12),
of the cutting roller (13) and of the transfer carousel (14) are synchronized so that
the gluing roller (12) acts in conjunction with the suction protrusion arrangements
(140) of the transfer carousel (14) to apply glue, and at least one knife (130) of
the cutting roller (13) is inserted cyclically into the recesses (140R) of the suction
protrusion arrangements (140) to cut the web (2) into labels (20).
