2.2 PRODUCT DESCRIPTION
The adhesive hot melt units described in this manual are used together with PREO
hoses and guns for the composition of a hot-melt application system, as illustrated
in figure 2:
Figure 2
The applicator (1) melts the hot-melt adhesive and keeps it at the desired
temperature.
Once the temperature has been reached, the melted adhesive is pumped through
the heated hoses (2) and is distributed onto the product by means of automatic
and/or manual guns (3).
The temperature control and adhesive distribution programme (if present) are
controlled by latest generation microprocessors.
Depending on the configurations installed, optional accessories may also be
present, making the entire system fully functional.
2.3 METHODS OF USE

manufactured for the following uses:
