B. Shims: none.C. Laminating Roller Pressure: 60 PSI, 410 kPa.D. Pull Roller Clutch Pressure: On, 80 PSI, 550 kPa.E. Pull Roller: Down, 60 PSI, 410 kPa.F. Speed: 4 to 6 fpmG. 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.

2. 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 andLaminate (Hot and Cold)Cold/Mount LaminateA. 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 LaminateA.Refer to charts 2-7, 2-7B, 2-8 and 2-8B.B.Encapsulate image. (see chart 2-7)
