Carbon-fiber rollers are usually made individually by filament winding or tape wrapping. But Epsilon Composite in France has a patented pultrusion process that is said to overcome ovalization problems usually associated with pultrusion. Because the pultruded rollers are made continuously (in diameters between 40 and 500 mm), they are said to be substantially less expensive than other carbon-fiber rollers that are produced one at a time. Pultruded rollers (sometimes over-braided with additional carbon fiber) reportedly are also stiffer, so smaller rollers can be used for wider webs without causing wrinkles. Epsilon began selling the pultruded rollers five years ago, primarily to OEM builders of blown and cast film lines. It has made rollers as wide as 6 meters and is aiming for up to 10 meters. +33 (556) 73 49 38 • www.epsilon-composite.com
