Roller gins are used primarily to gin extra long staple cotton varieties such as Pima S-6. They help to preserve the quality factors in lint that are desired by the spinning mill, mainly Long fibers with low counts of neps. Experiments were conducted to evaluate the feasibility of roller ginning extra long staple and certain upland smooth-leaf varieties grown in the Midsouth. The value and quality of the roller ginned cotton were compared to that processed on a saw-ginning system.
