A header for a crop harvester includes side drapers having a front edge adjacent the cutter bar and carrying crop to a discharge end roller at a center feed draper. A support arrangement carries the rear end of the discharge end roller to define an operating position in which an axis of the discharge end roller is at an angle to an axis of the outer end roller of the side draper with the rear end of the discharge end roller at a height below a height of the rear end of the outer end roller. This provides a main portion of the belt that lies in a common plane defined by an intermediate guide member and the outer end roller and a smaller portion of the draper belt between the guide member and the rear end of the discharge end roller which is twisted downwardly from the common plane.
