Adjust the supply roll unwind tension to remove any wrinkles from the
material. Do not use any more tension than needed or you may stretch the
material.
Begin to feed the images overlapping them or running scrap paper between
them. Be careful no to allow exposed adhesive to go into the rollers to avoid
wraparounds.
The roll feed option can be used in two ways with cold overlaminating. A roll
of printed material (one long image or many images) can be put on the roll
feed mandrel for lamination in one non-stop process. Or a roll of inexpensive
“release” paper can be run under the whole process to keep exposed
adhesive out of the nip while laminating a series of pieces.
For those customers who need cold lamination exclusively, Ledco
manufactures the Econocraft line of pressure-sensitive machines 25 to 50
inches wide. They can handle substrates up to an inch thick and as wide as
the particular machine.
