For contact free conveyance of thin, flexible substrates, the ideal alternative to traditional rollers. No contact means no manufacturing defects or flaws added during handling.
Air turns are an alternative to traditional contact rollers which utilizes porous media technology. For industries which require the conveyance of thin, flexible materials in roll-to-roll processes, the air turn is an exciting new development and one which any company should consider.
A traditional system for moving flexible substrates involves a contact conveyor system where direct tension between metal rollers is used to maintain flatness in your substrate. By applying carbon surface technology which pushes air through micro perforated holes in order to create a film of air, your substrate may travel up to 180° without ever contacting a roller. The air turns system can also be combined with radial air bearings to further drive material, allowing for variation in fly height, web tension and the ability to steer the material and even reverse direction if needed. Industry applications include printed electronics webs as well as paper conveyance.
