Isoten-brand vacuum rolls from Webex Inc. grip one side of a coated or adhesive-treated web for better control in transporting or pulling wet webs or isolating web tension.
The roll shells include a tungsten carbide plasma release coating. Other covering options include polymer compounds, stainless steel, mesh screen or, for delicate webs, felt.
Webex of Neenah, Wis., makes rolls from 12-20 inches, in diameters up to 160 inches, with web wrap angles from 30-80 degrees.
An adjustable-width vacuum zone option is ideal for varying web widths and helps maintain efficient, quiet operation.
