Slitting Dust Removal

Slitting dust removal System description The SLITstream dust removal system, for shear cut knife units, was developed especially to remove the cutting dust generated at the knife’s point of contact with the substrate. The specially designed dust extraction hood utilises the high velocity air flow generated within the system, which is directed at the top knife, to remove even the smallest of particles. The dust extraction is automatically engaged while the knife unit is energized. When the knife unit is switched off and in its rest position the hood completely encloses the knife. No manual adjustment...

Research has shown that utilising a vacuum system in the knife hood efficiently removes dust at the cutting point. The applied air flow volume, speed and direction are the key parameters which dramatically influence the dust removing efficiency. The high performance SLITstream technology generates an air flow of > 30 m/sec parallel to the knife against the web/sheet run direction. To achieve this we have developed an air channel inside the hood, in line with the knife. AUTO DC Technology® ionisation In most cases electrostatic charge present on the substrate surface is a major factor in increasing...
