DRAPER CANVAS WITH A SHAPED EDGE

摘要

A crop harvesting header with a cutter bar and a draper assembly has a draper canvas with an edge portion across a front edge to cooperate with a rearwardly projecting element of the cutter bar extending over the upper run of the draper canvas to engage the upper surface of the edge portion to form a seal to inhibit entry of dirt or crop between the cutter bar and the draper canvas. The edge portion of the canvas is thicker and is canted upwardly at an angle of the order of 10 to 20 degrees. There is also provided a bead on the canvas on the surface opposite the strip within the width of the strip. The arrangement can be symmetrical with a strip at each of the front and rear edges spanned by the slats extending between them.
