Webex Vacuum Rolls provide an ideal solution for applications in which nip rolls or contact with both sides of a web is not possible or desired. They are also an excellent tension isolation and control point ahead of flotation ovens, where webs are coated on both sides. By drawing one web surface into contact with the roll, Vacuum Rolls increase friction forces and help prevent web slippage.
Vacuum rolls have been proven in the most critical applications, such as the production of ultra-thin coated films, pressure sensitive papers, decorative products, adhesive tapes and optical film for the aerospace, biomedical and pharmaceutical industries.
Seamless designs incorporate a smooth, ultra-fine, seamless nickel screen that provides consistent grip across the entire web, without damaging even the most delicate coated materials.

Options Available:
Selectable vacuum zones (for wrap angles)
Polymer compound roll coverings
Seamless screens and felt screens (for delicate webs)
Stainless steel mesh screens
Cantilevered vacuum roll designs
Clean room designs
Custom vacuum supply connections
Variable Zone Width - improves vacuum performance while maintaining quiet operation
