The Celli Wingformer pilotted at Rieter Perfojet - First results

Alessandro Celli, Managing Director of Celli Nonwovens S.p.A (Italy) provided more information on the design of the new Wingformer air-lay head highlighting the significant differences from the established systems from Neumag (M&J) and Danweb.

Pulp was distributed through a thin flexible screen which could be cleaned on each rotation.

The system was now working in Rieter Perfojet's pilot plant

The use of wing-like fiber distribution elements gives uniquely uniform webs with very good MD/CD property ratios.

Web profiles show weight variability below 2% and most remarkably
this uniformity is maintained over air humidities ranging from 80% down to 30%.

Wingformed webs have been supported on spunbond and carded nonwovens
