Abstract: A high capacity saw type cotton gin having the usual ginning ribs, hulling ribs, and saw cylinder, and structure defining a roll box generally above the intervening zone between the ginning and hulling ribs having an entrance at the top of the intervening zone to receive cotton carried through the hulling ribs, wherein a rotatable perforated seed removal tube is located at the interior portion of the seed roll formed in the roll box near its axis of rotation having many peforations sized to pass ginned seeds therethrough into its interior while preventing passage of unginned seeds. The seed removal tube is continuously rotated in a direction corresponding to the direction of seed roll rotation and at a surface speed significantly exceeding the speed imparted to the immediately confronting seed roll portions by the saws, and screw conveyor structure as provided within the tube rotated to convey the ginned seeds in the tube outwardly through end portions of the tube.
