Abstract:
A material handling system has an input conduit section 12 having an input cross-sectional shape, an output conduit section 14 having an output cross-sectional shape that is different than the input cross-sectional shape, and a transition adaptor 18 connecting the input conduit section 12 and the output conduit section providing a transition between the input and output cross-sectional shapes. The transition adaptor includes a crown piece 20 that has an outer end having an elliptical sectional shape and an inner end. The transition adaptor includes a box piece 30 that has an inner end and an outer end 32 having a rectangular sectional shape, wherein the inner end of the crown piece mates with the inner end of the box piece. The box piece is formed by a first box half and a second box half 42, wherein each box half 40 is formed from a flat piece of metal and is formed by bending the box half 40 about bend lines.
