5.3 Former
The former (or folding box) wraps the film
completely around the product� Typically,
each different size product should have
its own former to produce an acceptable
package� The wings of the former can also be
adjusted�
5.4 Finseal
The finseal area consists of three pairs
of finwheels� The finwheels grip the two
mating edges of the film that is wrapped
around the product by the former and seal
them together with heat and pressure� At
the same time, the finwheels pull the film
from the backstand� The film carries the
product through the former and to the
endseal crimpers�
Typically, the first and third pair of
finwheels are cold, and the second pair
is heated� The heated finwheel will open
whenever the Stop button is pushed to
avoid melting the film, and then close
when the Start button is pushed� The cold
finwheels can be opened and closed with a
switch on the control panel�
