SPRAY COATING SYSTEM FOR FIBER WEB

摘要

The invention relates to a method for ensuring even and consistent application of a treating agent onto a fiber web. The method of the invention improves coating agent deposition process such that the fiber web is evenly coated using less raw material by improving the deposition method and atomization quality, better control of the deposition rate and improving the adhesion properties. The method collects a treating agent in a chamber directing the agent through a linear continuous nozzle onto a fiber web. The treating agent is electrostatically charged and ultrasonically nebulized before being directed towards the fiber web.
