Abstract
A method of forming carded fibers of different materials. A feed system has a plurality of separate laterally spaced chambers containing fibers of different materials. The different fibers are fed in separate laterally spaced paths into a carding apparatus having a plurality of rollers and cylinders each having laterally spaced sections in alignment with the laterally spaced paths to receive and maintain the different fibers in the laterally spaced paths thereon as they move through the carding apparatus. The different fibers are combined into a multi-fiber roving or web after they exit the carding apparatus. Depending on the composition of the different fibers, they may be combined by conveying them through a humidifying and heated chamber or chambers.
