After receiving roving from an intermediary simplex machine or fly frame, these devices expose the roving to a drafting process through which it is transformed to a desired thickness. The drafted roving is then twisted and wound onto a ring bobbin for packaging. The most commonly used devices in the yarn manufacturing process, these frames are small, accessible, and simpler to use than other methods of cotton spinning. ]]></dc:description></metadata>
