Interpretive Summary: Although roller ginning does the least amount of damage when separating the fiber from the seed, it is a slow process and consequently not used to gin upland cotton. Improving the efficiency of the roller-gin stand may make it economically feasible to roller gin upland cotton. An extractor-feeder and roller-gin stand were modified in an attempt to gin upland cotton at an elevated rate. A ginning rate of 4 bales-per-hour was obtained; this is in comparison to a standard rate of about 1 bale-per-hour. Providing a superior fiber to the textile industry benefits both the cotton producer, in higher demand for his product, and the consumer, by providing a quality fabric.
Technical Abstract: An extractor-feeder and roller-gin stand were modified in an attempt to gin upland cotton at an elevated rate. Modifications included speeding up the ginning roller, rotary knife, and cylinders on the extractor-feeder and increasing the force between the ginning roller and stationary knife. Choke-up problems were encountered early on with the extractor-feeder. Feeder modifications included enlarging the exit point on the top row of cleaning cylinders and adding a kicker cylinder at the exit point on the bottom row of cleaning cylinders. A ginning rate of 4 bales-per-hour was obtained; this is in comparison to a standard rate of about 1 bale-per-hour.
