Abstract:
A crop harvesting header comprising:a main frame structure extending across between two ends of the header across a width of the header for movement in a direction generally at right angles to the width across ground including a crop to be harvested; a crop receiving table carried on the main frame structure across the width of the header; a cutter bar across a front of the table carrying a cutter operable for cutting the crop as the header is moved forwardly across the ground for depositing the crop onto the table; and a crop transport system for moving the cut crop toward a discharge location of the header; the crop transport system including a crop transport draper having a first end roller, a second end roller parallel to and spaced from the first end roller and a draper canvas wrapped around the rollers for movement around the rollers longitudinally of the canvas in a crop transporting direction; the draper canvas having on its outer surface a plurality of generally transversely extending longitudinally spaced cleats attached to the outer surface and extending outwardly therefrom for engaging the cop and providing a longitudinal force on the crop; each cleat comprising a strip of resilient material attached to the outer surface such that the length of the strip is at an angle to a line at right angles to the longitudinal direction so that, as the strip passes around the rollers, one end of the strip passes around angularly in advance of the other end.
