What is the Rando Webber?

The Rando Webber is a precision-engineered system for forming airlaid nonwoven mats, designed to deliver uniform weight, consistent loft, and edge quality by ensuring a truly random orientation of fibers. It's been a cornerstone of Rando Machine’s airlaid technology since the late 1940s.

Webber


How does it work?

  • Opening & blending: Raw fibers (natural or synthetic) are opened, blended and individualized.

  • Feeding: The fiber mix is transported into the web-forming section.

  • Web formation: In the forming chamber, fibers are conveyed by high-velocity airstreams and centrifugal force onto a condenser cylinder or belt, resulting in a uniform nonwoven web.

Why choose a Rando Webber?

🎯 Key Advantages

  • Uniform weight, loft, and clean edges through true random fiber orientation.

  • Available in three condenser types:

    • SB: For coarse fibers (100+ denier)

    • SD: For fine fibers (nano to 100 denier)

    • SHL: Enables high-loft webs up to 10″ with simple HMI speed adjustments

  • Handles a wide range of fiber types: glass, synthetics, hemp, cotton, wood, and more.

  • Web basis weights can range from roughly 10 to 3,000 g/m² depending on the application.

Rando Machine: Legacy & Innovation

Founded in the 1940s, Rando Machine Corporation has led the way in nonwoven web-forming innovation since launching the first commercial 40″ Rando Webber in 1949. Based in Victor, New York, the company has expanded internationally and added a second manufacturing facility.

Their product portfolio includes:
