PA-5097-0-DW-USA SPRAY ARM CONFIGURATION AND METHOD OF FORMING THE SAME ABSTRACT OF THE DISCLOSURE A dishwasher spray arm having a top wall portion joined to a bottom wall portion. The wall portions are con- structed to be formed from identical Z-shaped sheet blanks. The wall portion edges define securing structure which, while being different in the two wall portions, are each preselected to closely fit within the Z-shaped sheet blank configuration. The Z-shaped blanks define a continuing series arranged to be cut from a strip of sheet material with a common edge be- tween successive blanks, effectively minimizing material wastage in the formation of the spray arm. In the illus- trated embodiment, the top wall portion defines further structure differing from that of the lower wall portion.
