Moss, Richard Mullen, Earl Boring, Jerry Hjellum, Alexander Christisen Title: "Duster Head And Method Of Making Same" ABSTRACT OF THE DISCLOSURE A duster head characterized by a central sleeve portion made from a strip of open mesh backing material, and a plurality of spaced apart longitudinally extending rows of yarn fringe material stitched thereto. To make the duster head, initially two inside rows of the fringe material are stitched to one side of a flat strip of the mesh backing in spaced relation from each other and from the edges of the backing before the backing is formed into the desired cylindrical shape. Both inside rows may extend almost the entire length of the backing material, terminating a short distance from each end thereof. However, preferably one of the inside rows is continued to the adjacent side edge of the backing near the upper end thereof to ensure more complete coverage of the backing by the fringe material in that region. The bottom raw edge of the backing is then serged to give it added strength. Next the mesh backing is folded along the middle intermediate the two inside rows of fringe material and back against itself along the entire length thereof and stitched together along the free edges and across one end to form such central sleeve portion closed at such one end and open at the other end. Then two outside rows of fringe material are stitched to the mesh backing on opposite sides thereof, one along the fold on one side of the mesh backing, and the other along the stitched edges on the opposite side of the mesh backing. The outside row of fringe material on the side opposite the inside row which is continued to the adjacent side edge of the backing is also desirably continued across the closed end of the central sleeve portion. A strip of fabric tape may also be stitched to the central sleeve portion along with one of the outside rows of fringe material adjacent the open end of the central sleeve portion to facilitate tying of the duster head to mop handle.
