Abstract: A cotton ginning apparatus having a rotating ginning saw drum for engaging and holding the fibers of the seed cotton. A cylinder-like serrated kicker device extends across the path of the seed cotton being admitted for directing the seed cotton onto the ginning saw cylinder. The seed cotton, being held upon the ginning saw cylinder, is brought into engagement with a rotating spiral shaped gin roller.
