Abstract
Standing crops severed by sickle mechanism at the leading edge of the machine are swept upwardly and rearwardly along a platform by a rotating reel to a lower, center-gathering auger and an upper, spaced distributing auger that converge the materials centrally and distribute them evenly across a discharge opening ahead of rearwardly positioned conditioning rolls. As severed materials pass through the machine, the flow is gently and progressively converged vertically due to the distances between the reel and the underlying platform, the two augers, and the conditioning rolls becoming progressively smaller. The lower auger serves as the primary central-gatherer, while the upper auger performs primarily as a distributor to spread materials which have been gathered by the lower auger over a substantial width of the discharge opening to the conditioning rolls, hence providing a generally uniformly thick and dense flow to the conditioner rolls instead of one which is congested and bunchy at opposite ends of the rolls.
