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 hand wheel 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.
When the top roller is equipped with a heater, heat activated materials can also be
processed with these rollers. The heater has a separate control unit, to set and control the
temperature (see section 5.1.2).
Four material shaft positions are standard on the machine. The two shaft positions at the
bottom 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 2 auto-grip shaft positions and a
splitter bar (idler). The rear shaft position is for unwinding film, the one on the front side for
winding e.g. the release liner.
The 2 shaft positions in the lower section are both unwind/wind-up positions, which gives
maximum flexibility for this section. So it can be used for supplying the bottom laminate
from rear to front, but also for supplying the images from front to rear (roll to roll).
For this Roll to Roll processing an optional Media unwind is available to support the image
supply roll.
When the optional Easy Feed in-feed table is installed, the media trough can be used as
media unwind.
