Combining roller ginning and lint cleaning into one machine

An experimental machine that combines the roller-ginning and lint-cleaning functions into one unit was tested. The ginning section of the machine is c onventional and the cleaning section consists of a cylinder-type cleaner. B ecause the ginned fiber is guided directly onto the cleaning cylinder witho ut forming a batt, a feed roll/feed bar assembly (which damages the fiber) is not required. The test consisted of comparing Pima lint cleaned with con ventional mill-type/air-jet cleaners to Pima lint cleaned with the experime ntal machine. There were no significant differences in fiber or yam quality between the two cleaning treatments. The experimental machine had more tra sh in the lint, more lint in the trash, and a lower cleaning efficiency tha n mill-type/air-jet cleaners, but turnout and bale value remained the same.
