Contactless static web rollers

  • There are numerous benefits of roll-to-roll frictionless web rollers, otherwise known as Air Turns. Some of the very basics are:
  • Precision control of web tension; you can advance the flexible web material with precision while maintaining tightly controlled web tension.
  • By adjusting the positive pressure to the air turn its possible to optimise air flow, web suspension and precision web tension.
  • Ability to convey the web material with no contact which is becoming particularly important within the flexible electronics sector.
  • Reduced maintenance and overhead (no moving parts e.g. bearings)
  • Non-static, less likely to build up collections of particle contaminants

Product Description

Through our relationship with OAV Air Bearings Inc. we can supply a truely innovative alternative to standard contact rollers for both web suspension and web tension control.

The OAV Air Turn features a porous media surface that is used to create a highly stiff cushion of air between the air turn and flexible web material. The novel design allows you to swich between 120 degree, 240 degree and 360 degree active zone depending on what wrap angle you need. 

Air turns can be retrofitted to replace existing traditional contact roll conveyors, either with the standard size or custom fitting to match the existing assembly. Contactless web handling reduces handling damage, material contamination and is fully anti-static, reducing costs associated with material scrap and rework. Costs associated with maintenance are reduced as well, with little scheduled maintenance and an indefinite operating life when run within recommended guidelines.

Application markets include flexible electronics, flexible photovoltaics, printed/flexible thin film batteries, anti-reflective coatings, barrier coatings, building products, chemical separation membranes.
