1. A harvesting header comprising
a frame , [ ;]
a forwardly disposed cutter bar assembly mounted on the frame, [ the cutter bar assembly operable to cut crop to generate cut crop material] ;
a rearwardly disposed draper deck assembly mounted on the frame and generally disposed rearwardly of the cutter bar assembly, the draper deck assembly comprising two spaced-apart rollers on which a continuous loop of draper canvas is mounted, said draper canvas having an upper moving conveyor surface being operable to move in a direction of movement that is transverse to a direction of travel of the harvesting header, said upper conveyor surface being operable to receive and move said cut crop material in said transverse direction of movement;
and a draper seal apparatus comprising:
a flexible strip oriented substantially parallel to the cutter bar assembly and substantially perpendicular to said direction of travel of the harvesting header, and substantially parallel to the direction of movement of the conveyor surface,
wherein the flexible strip has a forward edge and a rearward edge; and
a bracket mounted on the cutter bar assembly, the bracket extending substantially parallel to the direction of movement of the conveyor surface and said bracket being configured to secure the forward edge of the flexible strip adjacent an upper surface of the cutter bar assembly;
wherein the bracket extends rearwardly and is operable such that the rearward edge of the flexible strip is biased by the bracket into substantially continuous engagement with said upper surface of the draper canvas to provide a seal between the cutter bar assembly and the draper canvas.
