Coated Papers
Light Weight Coated or Middle Weight Coated
|
Mediumweight coating machines are not up to such high process speeds yet. This application is different and requires a different kind of steamshower configuration. The upstream application point is in the Fourdrinier or upstream of the suction roll. This improves the dryness into the press. The second steamshower is used in the press section on the suction roll or blowing directly on the felt transported web. Integrated felt heating is often used in this location to prevent heat losses. |
On machines with limited drying this application will produce a 6 to 9% production increase. The profile capabilities are excellent with 2-sigma values around 0.2%. The gloss level and profile are controlled with VIB Glosstech steamshowers applied in the calenders. Up to four calender steamshowers with profiling are installed in a multinip or super calender. In some applications full-width single zone actuators are installed to increase the gloss level. Page |
