Abstract
A high speed roller gin for seed cotton with variable length fibers has its components defined in accordance with the formula RKBS<(2SR-2MD)*RKSS/GRSS where, the rotary knife circumferential blade (RKBS) spacing is less than 2-times the seed release distance from the tip of the stationary knife (SR) minus 2-times the minimum distance the seed surfaces are allowed to approach the tip of the stationary knife (MD) multiplied by the rotary knife surface speed (RKSS) and divided by the ginning roller surface speed (GRSS). A seed cotton infeed slide further limits the exposure of the seed directly against the tip of the stationary knife to reduce the ginning of the undesirable short fibers. A process for using such gins is also disclosed.
