Abstract
In a combine harvester axial flow rotary separator, crop material is propelled in a generally spiral path as a relatively thin mat, maintained in contact with the inner wall of a cylindrical separator housing due to centrifugal force from the motion imparted to the mat by a rotor. The rotor, in each of several embodiments disclosed, carries finger-like elements which intermittently penetrate and positively propel portions of the mat without compressing it, the finger action and motion providing the desired axial displacement as well as circumferential movement of portions of the mat without relying on additional axial indexing aids such as guide vanes in the housing.
