Whether films, tarpaulin, mesh or other roll stock up to 180 kg, Nyala 3 can handle them all – even the heat-sensitive ones thanks to LED curing. And that across the full printing width of 3.2 metres. Setting up and changing rolls is easy, and once the job is started the machine continues working without supervision.
The spreading roller
It helps prevent crashes. It rests above the unwinding unit and smooths the material before it runs crease-free over the print bed and is rewound cleanly on the opposite side. One part of ensuring a flawless print image is stable system control, which continuously regulates the tension. Meanwhile, the spreading roller dissipates static charge from the material, aiding precise droplet placement. And another thing: when necessary, multiple colour layers can be applied in one pass and are absolutely register-true as a result.
The dual roll option
When it comes into play, the printer processes two rolls in parallel. You spotted it: this doubles the productivity. The system moves the widths of rolls weighing up to 100 kg smoothly over the print bed, feeding material via differential shafts that compensate minor winding unevenness. And should edge undulations develop, hold-down devices keep them in check.
Uneven material edges?
There is a remedy: hold down devices made of stainless steel. They are attached to the print bed in no time and prevent crashes and rejects by fixing the edges. Those of single rolls as well as those of dual rolls.
