Abstract
Belt guards that overlie the interface between a flexible cutterbar assembly and a flexible draper assembly of a harvesting header define an underlying void region that is sealed against the entry of crop residue by an upright dam wall that bears against the underside of the overhanging belt guards forward of the front edge of the upper run of the belt of the draper assembly. The upright dam wall is on the front extremity of flexible support panels that underlie the upper belt run and may be essentially rigid or provided with a resilient trim seal strip.
