ABSTRACT

An extractor-feeder and roller gin stand was 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. A ginning rate of 4 bales per hour was obtained; this is in comparison to a standard rate of about 1 bale per hour.
