2 DESCRIPTION
This chapter describes the machine and its operating basics.
2.1 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.
