| (54) | Heating head for thermally shrinking sealing capsules on bottle necks |
| (57) A heating member (30) integral with the head has a cylindrical heated cavity (30a)
in which the bottle neck with capsule is insertable. The head (20) is mountable on
a heating machine adapted to movably support the head between a resting position in
which the heating member (30) is axially spaced from the capsule, and an operative
position in which the heating member (30) surrounds the capsule and interacts with
it by heating it. A shield (32) having a tubular profile is insertable between the
heating member (30) and the bottle neck and is movably supported in an axial direction
with respect to the heating member (30) under control of actuator means (34), between
a resting position external to the heated cavity (30a), and an working position in
which it is interposed between the capsule and the heating member (30) and shields
the capsule from the heating action applied by the heating member (30).
