Slot nozzle assembly and shim plate

摘要

A slot nozzle assembly for extruding a fluid material includes a slot for extruding a fluid material, a plurality of material exit ports, and a plurality of material dispersion passages communicating with the slot and the plurality of material exit ports, respectively. The widths of the plurality of material dispersion passages in the longitudinal direction of the slot widen from the plurality of material exit ports toward the slot for extruding a fluid material essentially uniformly in the longitudinal direction of the slot.
