Abstract
A flexible header for a combine or swather includes a pair of wing sections which can flex relative to a central section. Each wing section carries a draper canvas for transporting a cut crop inwardly toward the central section. Beneath the inner ends of the drapers is mounted a further draper for transporting the crop rearwardly through an opening in the central frame into the feeder housing of the combine. Above the central draper is mounted a roller member having a central paddle portion and auger portions outside of the central portion for confining and directing the crop in cooperation with the central draper into the feeder housing. The pivot axis of each wing portion is inclined inwardly and forwardly so that the axes intersect at the sickle knife. This arrangement allows the manufacture of a large width flexible combine header.
