METHOD FOR PRODUCING A CARBON BAND FOR A CARBON INFRARED HEATER, METHOD FOR PRODUCING A CARBON INFRARED HEATER, AND CARBON INFRARED HEATER

摘要

A method is provided for reproducibly producing a carbon band twisted about its longitudinal axis. According to the method carbon fibers are fed into a processing device and are formed into a band-shaped preform having a centerline and an edge on both sides thereof. A shorter average fiber length is fed by the processing device when forming the centerline area than when forming the edges. The preform is subsequently further processed into the carbon band.
