Paper Coaters Double Line Speed with InfraredA roll-form paper products company faced a challenge: One of the company's products requires a water-based adhesive to be applied to paper prior to lamination. Previously, the adhesive was dried in a warm air oven, but colored adhesives yielded inconsistent results and an inferior-looking product. The short-term solution was a slowdown of the production line.

Working with application engineers from Heraeus Noblelight, Busford, Ga., the company devised a long term solution: a predrying system using carbon medium-wave heaters immediately before the existing warm air heaters. Infrared's quick on/off properties afford maximum control. The end result was a consistent and high quality product without production slowdowns.
