Webex Vacuum Rolls provide the ideal tension isolation and control point for your product. By pulling the web into intimate contact with the roll, Vacuum Rolls increase friction forces that help prevent web slippage. Used ahead of flotation ovens or in coating lines where nipping or contacting both sides of the web is not possible or desired, Vacuum Rolls are the solution for controlling your web.

An ultra-fine, seamless nickel screen is available that provides consistent grip across the entire width of the web, without damaging even the most delicate coated materials. Applications include the production of ultra-thin coated films, pressure sensitive papers, decorative products, adhesive coated films and optical film for the aerospace, biomedical and pharmaceutical industries.
