2-5 OPTIONS
•
Prefeed Slitter attachment
cuts material on the supply roll for application to
narrower substrates, for multiple-up production or for striping.
•
Bottom supply roll feed assembly
can be used when applying film or tape
to a long piece of material such as weeded vinyl signage. Tape the material
to be covered to a 3-inch supply roll core. Roll the material onto the core so
that it is not telescoped. The edges of the material at both ends of the rolls
should be even.
Put that core with the material to be laminated on the bottom roll feed mandrel
and line it up with the tape or film on the top supply roll mandrel. Once the
two webs (widths) of material are squared and aligned to each other, they will
stay aligned for the entire run.
The bottom roll feed mandrel is also useful when applying tape or film wider
than the materials being covered. In this case, put a roll of “sacrifice” paper
(such as wrapping paper) on the bottom roll feed mandrel. The roll of
“release paper” should be wider than the tape or film. This width allows the
tape or film on either side of the material being laminated to stick to the paper.
The “release paper” serves to keep adhesive off the bottom laminating roller,
prevent wraparounds on the bottom laminating roll, and to keep adhesive
from sticking to the exit table, which would ruin the job as material jams
against the stoppage. The signage or other material can then be trimmed out
of the sandwich formed by the tape or film and the release paper.
In other jobs where the tape or film is not wider than the material being
covered, it is advisable to overlap pieces or put scrap paper between pieces
to serve as “release paper” for the reasons listed above. Scrap paper can
also be used at the beginning and end of a job for the same purpose.

Roll Feed
The roll feed option allows you to feed a roll of substrate
through the laminator when using the lower supply roll for either release
paper or another laminate. This option attaches directly to the feed table.
