A draper having an additional strip of a resilient material attached on to the outer surface of the base layer at the front edge is connected at ends to form a continuous loop by a coupling comprising a first and second end edge which are turned so as to stand upwardly from the band and a clamping assembly clamping the upwardly standing edges together. The additional band at each end of the canvas is recessed from the outer surface and a strip portion formed of a flexible continuous strip material extending longitudinally of the additional band connects the two ends. The strip is bolted at each end to the recessed portion and has a thickness so that its outer surface is slightly less than that of the additional band thus forming in effect a continuation of the band bridging the ends of the canvas.
