Dust problems with V-knifes & damages to anvil roller.
This issue does only relate to machine with V-knifes. Rotary knife systems does not have dust problems.
The standard V-knife has an angel of 45
, this can generate dust with some materials. If there is a
problem, we can deliver a knife with a 30
angel to fix this problem. This knife is sharper and have a
shorter life cycle. Remember to limit the air-pressure to a minimum (what is needed to just cut through
the paper).

Die cut station adjustment and alignment
The die cut must have washers on each side to prevent lateral movement and damage to the cylinders.
Remember when changing the die cut cylinders you need to make an adjustment.
Centering the die cut cylinder extends support bearings lifespan, but it also avoids crushing the inductive
sensor on the backside of the sprocket. Use an allen 2,5mm and gently turn clockwise the pointed screws
Untill there are some slight pressure in the allentool. Its easy to feel when die cut cylinder is not ingaged
in gear.
Pay special attention to the rear of the gear on the die cut cylinder, that the inductive sensor does not hit
the cylinder gear. There should be 1-2 mm gap.
