Corona Treater Station Design & Construction: Meeting the Blown Film Challenge, 1996 Polymers, Laminations & Coatings Conference Proceedings
Treater station construction has undergone significant changes to accommodate lighter webs, higher line speed operation and advanced substrates. The range of developments has included the requirement for nips at the treater roll, using the treater roll as a “pull roll” and modifying the treater station design to reduce wrinkling and “backside” treatment. Several different techniques were attempted to reduce wrinkling and backside treatment, but one, dual dielectric/coated roll technology has become by far the primary method used to overcome these problems. Various technologies are discussed and the current state-of-the-art in equipment, control parameters and applications are explained.
