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. A lid locked to the vender is provided with engaging means which engages a bracket affixed to the securing post. The laundry items are sorted by way of their individual information stored on the carriers, moved into corresponding storage sections of the storage means and at the same time are both sorted and formed into laundry batches. The joint portion is disposed in both of the first through-penetrating passageway and the second through-penetrating passageway, and engaged with the front fastening part and the rear fastening part.
