Web-gripping vacuum rolls from Webex

Isoten vacuum rolls from Webex grip one side of a coated or adhesive-treated web for better control in transporting or pulling wet webs and/or isolating web tension. Isoten standard vacuum roll shells include a tungsten carbide plasma release coating that is claimed to provide an excellent general-purpose shell surface.

Other roll covering options include polymer compounds, stainless steel mesh screen or felt for delicate webs, and a rotary gravure seamless screen for magnetic media and optically clear applications. Rolls are readily available from 12" to 20" in diameters up to 160", with web wrap angles from 30 to 180 degrees.

Isoten vacuum belts, able to accommodate flat surface contact, help establish a specific web path and tension zones, and can be stretched length-wise to increase sustainable tension. An adjustable width vacuum zone option is ideal for varying web widths and helps maintain efficient, quiet operation. Heat transfer vacuum rolls are also available that combine vacuum roll web control with heating or chilling of the web.
