A harvesting header having a flexible cutterbar assembly utilizes draper belts behind the cutterbar assembly to gently consolidate the severed crop materials and deliver them to a point of discharge and delivery, such as to the feederhouse of a combine harvester. One embodiment has draper assemblies
A harvesting header having a flexible cutterbar assembly utilizes draper belts behind the cutterbar assembly to gently consolidate the severed crop materials and deliver them to a point of discharge and delivery, such as to the feederhouse of a combine harvester. One embodiment has draper assemblies and a central conveyor fixed relative to the flexible cutterbar assembly, while another has the draper assemblies and central conveyer flexible with the cutterbar assembly.

The invention claimed is: 1. A harvesting header operable to harvest a crop, said harvesting header operable to be supported by a feederhouse that presents an open end configured to receive severed crop materials, said harvesting header comprising: a header frame operable to be mounted to the feederhouse; a cutterbar assembly mounted to the header frame to extend lengthwise in a lateral direction relative to the normal direction of travel of the header; a draper assembly supported on the header frame behind the cutterbar assembly to receive crop severed by the cutterbar assembly, said draper assembly including a pair of side conveyors and a fore-and-aft draper located between the side conveyors, said side conveyors configured to receive severed crop materials from the cutterbar assembly and convey the materials laterally to the fore-and-aft draper, said fore-and-aft draper presenting upper and lower runs, with the upper run being configured to move the severed crop materials rearwardly, said fore-and-aft draper presenting a rear margin defined at the rearmost junction of the upper and lower runs, said rear margin spaced forwardly from the open end of the feederhouse when the header frame is mounted thereto, with a transition area being defined between the rear margin and the open end, said header frame presenting a discharge opening aligned with the open end of the feederhouse when the header frame is mounted thereto, with the transition area extending through the discharge opening; and a central crop-conveying member rotatably mounted relative to the header frame for rotation about a lateral axis to consolidate severed crop materials from the side conveyors and the fore-and-aft draper into a low-profile mat, with the member extending into the discharge opening to feed the mat along the transition area, said crop-conveying member extending forwardly of the discharge opening and overhanging the rear margin of the fore-and-aft draper; and a floor pan at least partly defines the transition area and presents a forwardmost edge adjacent to and spaced rearwardly of the rear margin, said forwardmost edge being located above the lower run to direct severed crop materials from the upper run and to facilitate crop material flow through the transition area. 2. The harvesting header as claimed in claim 1, said header frame including upper and lower beams that cooperatively present an upright frame centerline axis, said lateral axis being spaced forwardly of the upright frame axis. 3. The harvesting header as claimed in claim 2, said rear margin of the fore-and-aft draper spaced forwardly of the lateral axis. 4. The harvesting header as claimed in claim 2, said crop-conveying member positioned between the beams and thereby vertically positioned within the discharge opening to project forwardly and rearwardly therefrom. 5. The harvesting header as claimed in claim 1, said side conveyors each comprising a side draper that includes a side draper belt presenting a laterally inwardly moving run for conveying crop materials laterally inwardly to the fore-and-aft draper. 6. The harvesting header as claimed in claim 5, said side drapers cooperatively forming a receiving opening therebetween, with the fore-and-aft draper being spaced within the receiving opening. 7. The harvesting header as claimed in claim 6, said crop-conveying member being positioned above the receiving opening. 8. The harvesting header as claimed in claim 7, said crop-conveying member substantially spanning the receiving opening. 9. The harvesting header as claimed in claim 1, said cutterbar assembly being operable to flex along the length thereof in response to changes in terrain as the header is advanced, said draper assembly supported on the header frame behind the cutterbar assembly to flex therewith, said fore-and-aft draper including a draper frame swingably supported on the header frame at a draper pivot to project forwardly therefrom, said fore-and-aft draper including a draper belt supported on the draper frame to present a rearwardly moving run for conveying the crop rearwardly, said draper frame presenting a forward margin and being coupled to the cutterbar assembly adjacent the forward margin such that the draper frame is caused to swing relative to the header frame as the cutterbar assembly flexes up and down. 10. The harvesting header as claimed in claim 9, said draper pivot being spaced below the lateral axis. 11. The harvesting header as claimed in claim 9, said header frame including upper and lower beams that cooperatively present an upright frame centerline axis, said lateral axis being spaced forwardly of the upright frame axis and rearwardly of the draper pivot. 12. The harvesting header as claimed in claim 9; and a plurality of laterally spaced apart support arms being attached to and cooperatively supporting the flexible cutterbar assembly, said support arms being pivotally coupled to the header frame for swinging movement about a laterally extending axis so that the flexible cutterbar assembly is operable to flex. 13. The harvesting header as claimed in claim 12, said side conveyors each comprising a side draper that includes a side draper belt presenting a laterally inwardly moving run for conveying crop materials laterally inwardly to the fore-and-aft draper, said flexible cutterbar assembly presenting a center section defined along the forward margin of the fore-and-aft draper and a pair of side sections defined along the side drapers, with multiple ones of the support arms being associated with each of the cutterbar assembly side sections. 14. The harvesting header as claimed in claim 13, said support arms associated with each side section including a pair of laterally outermost support arms and at least one intermediate support arm located between the outermost support arms. 15. The harvesting header as claimed in claim 14, each of said side drapers being carried on the corresponding outermost support arms and the at least one intermediate support arm. 16. The harvesting header as claimed in claim 1, said header frame including an adaptor frame that substantially surrounds the discharge opening and presents a feederhouse-engaging surface operable for mounting the header frame to the feederhouse. 17. The harvesting header as claimed in claim 1, said floor pan attached to the header frame and extending rearwardly through the discharge opening from the fore-and-aft draper to support severed crop materials traveling from the fore-and-aft draper to the open end, with the floor pan thereby defining the transition area. 18. The harvesting header as claimed in claim 1, said central crop-conveying member comprising a rotating center-gathering auger.
