F.
Speed: 4 to 6 fpm
G.
Top Roll Temperature: 220-230 degrees F (90 -
110 degrees C).
H.
Bottom Roll Temperature: 220-230 degrees F (90 -
110 degrees C).
I.
Cooling: Optional.
J.
Use of the rear rewind for the finished material is
optional. It is a good procedure for long runs. If a
rewind is used in this application the clutch pressure
should be 15 PSI.

Procedure:
A.
Feed the work into the nip with the leading edge
tight and entering the nip evenly from side to side. For
thin paper from electrostatic printers in roll form, it is
best to fold over the leading edge approximately 6
inches to create a square leading edge.
Two-Pass Mount and
Laminate (Hot and Cold)
Cold/Mount Laminate
A.
See charts 2-5, 2-5B, 2-6 and 2-6B for settings.
B.
Assure that the mounting film from the bottom side
has the sticky adhesive side riding up around the outside
of the bottom laminating roller.
Procedure, Pass 1:
A.
Run the print through to apply adhesive and
laminate.
B.
Trim to slightly larger than the desired finished size.
WARNING:
Take care when repositioning rewind/unwind
shafts or other heavy parts or materials, used in
the various web-up patterns. They are heavy and
can cause injury to fingers and/or toes if not
handled properly.
Procedure, Pass 2:
A.
Prepare to put the print through a second time to
mount the print to the substrate. — anything from
wood, to Masonite, to Gator foam. Start by setting the
shims to the appropriate spacing for the material used.
B.
Trim the board to the size of the print.
C.
Align the work to the board and assure an exact fit.
Place weights on the center of the print to assure that it
does not move relative to the board during the next
steps.
D.
Raise one end of the print and peel back
approximately two inches of the liner to expose the
adhesive that was applied to the print in pass 1. Fold it
under. Lay the print back down evenly and extremely
flat. From the center outward, tack the exposed
adhesive to the substrate.
E.
Position the piece so that the end with the liner
peeled back is facing the nip. Insert the first one inch of
the board into the nip.
F.
Very carefully wrap the print back and over the top
laminating roll. Be sure there are no wrinkles in the nip
area. Carefully peel off the liner as the board progresses
through the laminator.
G.
Trim the piece to the finished size.
Hot/Mount Laminate
