Illustration 7.1
After leaving the creaser, the bag is partially folded so that the top flap (with the pre-applied glue)
is bent 90
o
or parallel with the floor. (
Illustration 7.2
) The top surface of the hot air manifold has
a series of holes for the hot air to exit the manifold and melt the glue on the flap of the bag. The
folder holds the flap horizontally over the holes.
After the manifold, the folder
continues bending the heated
flap another 90
o
to complete the
fold. The adhesive begins to
make contact with the outer bag
surface as the fold is completed
and the bag enters the
compression area of the
machine. The wide
compression belts guide the bag
top between the compression
belts. The belts press the flap
firmly against the bag, to force
the adhesive to penetrate the bag
fibers. The completed fold and
compression yield a sharp, clean
fold with a strong bond.
