5-2 Tunnel temperature adjustment
The tunnel temperature is adjusted by a simple linear potentiometer.
The temperature must be adjusted, according to the kind of used film, in order to
get a good shrinkage result.
When the potentiometer is turned clockwise, the setting of the temperature value
is increased; on the contrary, this value is decreased, when the potentiometer is
turned anti clockwise.
The display over the potentiometer shows the temperature value .
When the potentiometer is turned clockwise, at the bottom, on the right side of
the potentiometer itself two red lights are on, thus showing, that the two heating groups

are heating up the tunnel.
The temperature settings are indicated on the scale.
5-3 Sealing time adjustment
The sealing time increasing or decreasing allows to cut and seal different kinds of film.
This sealing impulse time is increased, when the potentiometer is turned clockwise and it is
decreased, when the potentiometer is moved anti clockwise.
It is an impulse time, because the sealing blade is normally cold and it is heated only when the
sealing arm is closed.
