An Isoten Vacuum Roll pulls the web into intimate contact with the roll, increasing friction forces that help prevent web slippage. The result is a highly effective web control device that can handle much lower tensions and much higher tension differentials.

Movable deckle plates adjust the vacuum zone to match variable web widths. This improves vacuum performance while maintaining quiet operation. Deckle positioning can be adjusted manually or through automated mechanics.
Shell Coatings, Coverings and Screens
The tungsten carbide plasma coating of standard Isoten vacuum roll surfaces is a durable, all-purpose finish with good traction and release properties. Rubber (polymer compound) coatings can be provided when increased traction is necessary.
Stainless steel mesh screens or felt shell coverings are available to prevent marking of delicate webs. Stainless steel woven screens are available in thread counts per inch up to 120 x 120. Seams are helical and are manually "stoned" to present a very smooth surface to the web.

Vacuum Supply Systems
Webex offers exhausters in support of all Isoten vacuum roll applications, including both fans and regenerative blowers. Simply ask that a blower be included as an option when requesting your vacuum roll quotation, specify power available, and note it an explosion-proof motor is required.
Client approvals are required on all roll drawings prior to manufacturing to ensure your specifications are completely met. Talk to us about your vacuum roll application. We can answer your questions and help ensure you are specifying the right product for the right application.
