A method of producing noodles by cutting a noodle sheet into noodle shapes using a rotary cutting device including at least a pair of cutting rollers, scraping members, and an air current supply means. A noodle sheet is passed between the cutting rollers to cut the noodle sheet into noodle shapes, the noodles are scraped from the cutting rollers by the scraping members and are separated into upper and lower noodle bundles, and an air current is supplied to the cut noodles from the air current supply means. The production method is capable of consistently producing substantially straight noodles that do not have a significantly waved shape in the longitudinal direction thereof, even if used in a mass production line.
