Webex Carbon Fiber Rolls Have Custom Finishes

Published: June 07, 2013

NEENAH, WI | Webex offers carbon fiber rolls with an extra-thick, outer epoxy layer said to protect the rolls’ strength layers of wound filaments while providing the ideal surface for custom roll treatments. 

The surface layer is made from a hardened gauze/epoxy winding formed to thicknesses of 0.0020–0.0050 in. as needed. This “sacrificial layer” allows the roll to be machined with grooves or other surface modifications to exacting tolerances, like a steel or aluminum roll, without affecting the structural layers of carbon fiber winding. The added thickness is said to provide a highly durable surface that, for most applications, does not require additional protective coatings.

These custom rolls are also available with a sprayed application of metal, paint, or silicone coatings to create a high-performance release surface, company says. Available in both live and dead shaft designs, carbon fiber custom coated rolls are said to be lighter and stronger than conventional aluminum rolls of similar dimensions and yield lower inertia ratings and lower breakaway torques.
