Abstract: A method and apparatus for ginning harvested seed cotton comprising the steps of: introducing harvested seed cotton including lint and seed on to the upper surface of a lower rotating plate (3); rotating said plate to thereby carry said harvested seed cotton towards the leading edge (29) of a knife positioned at a defined distance above said lower rotating plate such that the cotton seed is drawn/combed under the knife edge (27); extracting line separated from said harvested seed cotton from a rearward facing edge of said knife; and collecting said seed from the leading edge of the knife.

Abstract: A linear belt flight has an upper high friction surface to which seed cotton adheres for conveyance to a transverse fixedly positioned knife adjacently above the belt flight; the cotton fibers move beneath the knife to separate the fibers from the seed which move onto the upper surface of the knife. A rotary knife engages the separated seed on the upper surface of the fixedly positioned knife and propels the seed rearwardly onto an auger conveyor for removal of the seed while air doffing means removes the fiber from the upper surface of the linear belt flight downstream of the knife.

Abstract: A roller cotton gin including a ginning roller and a stationary knife to which seed cotton is conveyed by the friction surface of the ginning roller for separating lint fibers from the cotton seed, and a rotary stripping blade device adjacent the stationary knife having blades forming channel-like pockets therebetween for receiving the seed cotton deposited on the surface of the ginning roller and advanced to the zone of the stationary knife.

Abstract: A roller cotton gin including a ginning roller and a stationary knife to which seed cotton is conveyed by the friction surface of the ginning roller for separating lint fibers from the cotton seed, and a rotary stripping blade device adjacent the stationary knife formed from a square cross section bar having V-shaped grooves axially spanning each face adjacent the corners providing blade formations for advancing the seed cotton deposited on the surface of the ginning roller to the zone of the stationary knife.

Abstract: A roller gin is most effectively used for processing fine-stapled cottons.The roller gin comprises a ginning roller, a sectional knife urged against the surface thereof and actuated by a vibrator so that the sections of the knife are oscillating in anti-phase, and a stripping organ also made sectional and provided with vanes, the vanes of the changeable sections being turned through an angle sufficient for each vane to cooperate with an appropriate section of the knife and the stripping organ being rigidly coupled to the vibrator through a gearing ratio multiple of the number of the vanes in each section.Such a roller gin increases the efficiency of ginning, enhances the quality thereof and makes it possible to handle any class of cotton irrespective of the degree of attachment of the fibers to the seeds.
