5. Working with laminator
5.1 Selecting suitable foils
The manufacturer and the distributor recommend using foils in rolls with internal
diameter of 75 mm and with width depending on the width of the processed (laminated)
material. When selecting the foil, it is necessary to comply with the recommendations of the
distributor. Commonly supplied widths of foil are included in the price list of the distribution
company. All machines may be used for lamination of rolls narrower than the maximum
working width of the equipment. In this case, it is necessary to comply with the principle that
the left edge of the lamination foil is closest to the left margin of the heated rollers, because in
these places (on the left side of the heated roller), heat sensors are located. Only when
laminating very thick paper sheets (exceeding 350 g/m2) and smaller width than the width of
the roller, we recommend to move the foil roll to the center of the roller and laminate along
the axis of the equipment. This will enable equal pressure of the roller along the entire width
of the laminated sheet. Also, for lamination of narrower foils and sheets of paper on the
laminator *.
Material – polypropylene of width of 24 – 30 µm, or nylon of width of 32 µm.
Polyester of width up to 125 µm may also be laminated on the equipment, but with reduced
output and when it is not possible to use the separator. Separation of sheets is possible only by
manual cutting.

Installation of the foil
Install the foil in accordance with the figure in the instruction manual. Before installing the
foil, it is necessary to make sure where the glue is placed on the foil. On the heated rollers, the
foil roll must be inserted in such a manner so that the glue does not enter in contact with the
heated roller.
POLY IN
– the glue is on the inside side of the foil
POLY OUT
– the glue is on the outside side of the foil

Before installing the foil on the arbor, it is necessary to dismantle the friction brake (C) and,
after the installation of the foil, it is necessary to install it back. Safeguard the delimitation
wheels (E).
* FOLIANT 720HP – the roll with foil must be placed in the longitudinal axis of the
equipment, the uncovered rollers must be cooled by ventilators.
