Abstract:
Apparatus for dispensing a fluid onto a substrate, said apparatus comprising:a fluid dispensing head having a dispensing surface, an entrance edge and an exit edge; and means for transporting a substrate generally parallel and adjacent to said surface in a direction from said entrance edge to said exit edge; and wherein said head has a plurality of rows of holes through said surface to dispense said fluid onto said substrate, the holes of each row being generally uniformly spaced from each other, each of said rows including a multiplicity of said holes and being generally transverse to the transport direction, and each row being offset in the transverse direction relative to the other row(s) such that if imaginary lines are drawn in the transport direction through centers of respective holes, there is a generally constant offset in said transverse direction between every two successive imaginary lines.
