ENGLISH
The T series tunnel has been
designed to heat shrink the film.
The tunnel's conveyor belt is
connected to the machine's belt
FP end BP. For a good
packaging, film sealing must
take place at half the product
height. The raising (or the
lowering) of the belt implicates
the regulation of the tunnel's
curtain, this is necessary as it is
essential not to disperse heat
during the heat-shrinking
operation.
Adjust the height of the T650
tunnel and lock the belt with the
two screws 1.
3.1 TUNNEL IDENTIFICATION
Fig. 3.1.1
On the rear of every tunnel
there is a data plate showing
the EC marking, the main
technical data such as model,
serial number, power, etc., that
will be notified to the builder in
case of problems.
3.2 SHRINKING
Film shrinking is obtained in the oven and is produced by the forced circulation of hot
air around the packaging. Air heating is obtained by making the same go through a
group of thermo-controlled resistors: a centrifugal fan moves the air. If the sealing
breaks during the shrinking it is possible to increase the speed of the belt or to lower
the temperature of the resistors by acting on the tunnel's control panel. Air heating is
