Abstract
A combine gathering belt assembly has a pair of continuous sprocket chains each supported on rotatable sprockets at their opposite ends, and having spaced parallel inner traveling chain portions. A plurality of flexible spaced belt segments are secured to the sprocket chains. The belt segments on one chain are staggered with respect to the belt segments on the other chain. Each belt segment has a base end adjacent the chain to which it is attached, and an outer end extending forwardly while between the spaced parallel inner traveling chain portions. The belt segments are of such size and spacing that an outer end of a belt segment on one chain closes on a base end of a belt segment on the opposite chain while in the spaced parallel inner traveling chain portions. The closed belt segments then open up as they move around the rotatable sprockets on one discharge end of chains to release plant segments that may be bound by opposite belt segments while moving through the spaced parallel inner chain portions.
