Abstract
A filter-manufacturing machine comprises spray nozzles located on both sides of a feeding path of sheet material made of filter fibers, respectively, and the spray nozzles each have a line of spray holes of a liquid binder with high viscosity and a plurality of air jetting openings for jetting compressed air. The liquid binder sprayed from the lines of the spray holes is subdivided into particles by the compressed air, thereby spraying the particles of the liquid binder evenly on both surfaces of the sheet material.
