In: Misr Journal of Agricultural Engineering 2002.v.19(4)Summary: A new designed extractor-feeder machine was built to replace both the inefficient belt and cylinder methods that are in use in feeding the ginstands with seed cotton. The seed cottons of seven varieties were fed by the new machine to the ginstand at different speeds (0.6, 0.7,0.8.0.9, and 1.0 rpm). The results obtained show that fixing the speed of the extractor feeder at 0.7 rpm (0.0022 m/s), resulted in increasing the ginstand capacity to about 35 %, 42.27 % and 68.5% higher than manual feeding, the cylinder and the belt methods, respectively. Meanwhile, this speed decreased .the ginning time and non-lint content and improved the lint grade and fiber brightness. The extractor feeder machine did not affect the ginning outturn, fiber length parameters, fiber elongation, fiber strength, micronaire reading or seed cracking.
