Coating unit for simultaneous double-sided siliconizing

Coating unit for simultaneous… Kroenert, a global leader in the manufacture of customized coating, printing and laminating systems, is introducing the first coating unit for simultaneously siliconizing both sides of a web with solvent-free silicones. Expanding its range of products, Kroenert has redesigned a roll-to-roll system especially for this purpose. This coating unit can be included in new plants or retrofitted in existing facilities. Retrofits offer a special advantage: the flotation dryer already installed in many plants can be used for the non-contact transport of webs and combined with a non-contact air turn in front of the dryer. This feature cuts down on costs for equipment and operations and minimizes environmental impact. The process of double-sided siliconizing is especially suitable for paper webs used as release liners for adhesive tapes, for example, and for graphic products.

The simultaneous coating of the front and back of paper webs substantially prevents paper from drying out and the coating machine can be considerably shorter in length, taking up less space. Moreover, the system requires less operators, allowing one person to oversee two coatings at the same time. As only one dryer is needed, this process is very resource-efficient and consumes less energy. The siliconizing unit can also be utilized for one-sided coating and operate flexibly with other substrates and silicones at any time.

“Our new siliconizing unit, which simultaneously coats both sides of a web using roll-to-roll technology, has proven successful in practice and is an outstanding addition to our portfolio of top-quality products, which to date includes systems primarily with gravure rollers for double-sided coating”, says Wolfram Szczepaniak, Head of Technology at Kroenert. “The expansion of our product lines of efficient coating solutions is an ongoing process and we are already testing the next developments in our Technology Centre.”

Since 1903 Kroenert is developing, engineering and manufacturing customized turnkey line solutions in the field of coating technology for web-like materials such as paper, foil and film. Besides complete lines, a comprehensive range of winders and rewinders, more than 60 modular coating systems and advanced drying technology, humidifiers and laminating systems can be designed and delivered. The products manufactured on Kroenert machines are used in the flexible packaging industry, for technical applications and renewable energies as well as environmental protection. Kroenert’s headquarters are in Hamburg, Germany, where its own research and test centres are also located. It is represented by agents across the globe. Kroenert and its affiliated companies together employ about 350 people.
