A criss cross coating hopper 10 is provided which is capable of producing uniform flow distribution patterns. The hopper 10 is comprised of a first and second hopper halves 12,14. First and second hopper halves 12,14 each have a first and second planar surface 20,40, respectively, adjoining a first and second cavity 22,42, respectively, each cavity 22,42 having a land surface 28,50 near the entrance end 26,48 and exit end 24,46. Inserts 62,64 are positioned against the land surface 60 of the first hopper half 12 and the land surface 50 of the second hopper half 14, respectively. The first and second hopper halves 12,14 and the inserts 62,64 cooperate to form an exit slot 69 recessed into first and second planar surfaces 20,40.
