General description

The machine described in this manual is a mono-directional machine dedicated for
processing pressure sensitive or heat activated materials.
While feeding through images and the coating films, the two silicone coated main rollers
generate the pressure.
The area where the upper and lower main roller meet is called the "nip". The upper main
roller can be moved up or down manually, so the nip can be varied to feed materials of
various thicknesses. A mechanical read-out shows the value set.
The nip setting handwheel also sets the pressure for the laminating process.
The lower main roller is motor driven. The speed can be manually set between zero and a
given maximum value.
Because both rollers are equipped with a heater, heat activated materials can also be
processed with these rollers. Each roller has its own temperature control unit, so top and
bottom roller temperature must be set separately.
In addition to the main rollers a pull roller set is provided to prevent warping of
encapsulation results. (This set is not suited for cold lamination processes.)
A cooling device is installed in front of the pull roller set. When both heaters are turned on,
the cooling device will prevent the pull rollers from warming up too much and therefore
prevents the encapsulation result from showing wrinkles.
Five material shaft positions are standard on the machine. Three of these shaft positions
can function as both an unwind or as a wind-up position, which makes the machine more
flexible and enables roll to roll processing for some processes.
The machine can be divided into an upper and a lower section.
The upper section, above the in-feed table, consists of 3 auto-grip shaft positions and a
splitter bar (idler).
The top shaft position is for unwinding film, the one on the front side for winding e.g. the
release liner. The third shaft position is an unwind/wind-up position, which enables more
flexibility in the use of this section.
The 2 shaft positions in the lower section are both unwind/wind-up positions, which gives
maximum flexibility for this section.
When laminating media from a roll it is very important to feed the media correctly into the
nip, otherwise it will run out of the foil width. For this purpose the in-feed table media guide
and table rollers are added to the in-feed table.
When not needed the in-feed table rollers and the image guide can be lowered into the
table.
A media roll can be placed in the trough at the front end of the table or on an unwind shaft
position.
