(57) An automatic labelling machine for incorporation to case packaging machines in general,
of both the continuous and intermittent feed types using pushers, and including a
printer head (9) and a wedge element (21) operative to break labels (5a) away from
a carrier web (11) being paid out from a web storage reel, and a carrier web take-up
reel, comprising a feeder (14) mounted rotatable about a parallel axis to the case

a cam profile (18a) and carry a box-like body (19) alternately subjected to a vacuum
and adapted to receive one label (5a) from said label detaching wedge element (21),
transfer it to an area of application thereof to a case moving along a case transport
line, and apply it by pressure to said case; also provided being a means of rotating
