Hamburg, Germany; April 27, 2004 -- Dust is an inevitable consequence of converting paper and one of the most common causes of production stoppages and loss of quality in printing presses and copying equipment. Deposited on paper during the sheeting, rolling and decurling processes, this dust then infiltrates printing presses and copying equipment where it contaminates rubber blankets, inking units and rollers, causing poor quality and the need for frequent cleaning.
At drupa 2004, Korber PaperLink is offering a novel solution to the dust problem. The company's new Schneider XT system allows paper mills and converters to virtually eliminate dust from webs and sheets, and in the process, offer their clients an additional selling argument.
In the Schneider XT system, dust is removed using specially directed compressed air to produce a locally limited vacuum at the surface of the paper. It works by making no contact at all, thus sparing the surface of the paper from damage. The electrostatic and van der Waals forces that bind the dust to the paper are neutralized in the vacuum. The dust is then blown from the paper using compressed air and drawn off, into the air extraction duct of the dust removal head.
