ABSTRACT:
A doffer for use with a spindle type cotton harvester is provided which has non-radial lugs to provide a better distribution of stripping and unwrapping force components for enhanced doffing action. The leading edges of the lugs are curved and are angled with respect to the radial direction to provide a scissors action relative to the spindles as the doffer rotates for improved doffing and wear distribution. The lugs provide an immediate unwrapping component upon initial contact with the cotton-wrapped spindles, with less stripping action to reduce the amount of cotton forced between the spindles and the doffer. In another embodiment of the invention, lugs with different pitches are supported in alternating fashion so that the action of the lugs with the greatest pitch provide a large unwrapping force and the smaller pitched lugs provide a large stripping force. The rear portions of the lugs are curved for increased cotton throwing clearance.
