ABSTRACT:
A method for filling a muffler with a fibrous material is disclosed. The muffler includes partitions which form a first chamber and second chamber, and a first muffler pipe having an outlet end. A filling aperture at one end of the second muffler pipe is positioned in the first muffler chamber. The second muffler pipe has a filling sleeve therein, the filling sleeve having a filling discharge opening that coordinates with the filling aperture of the second muffler pipe. The first muffler chamber is filled with fibrous material by applying a vacuum source to the first muffler pipe, which draws the fibrous material through the filling aperture. The filling aperture of the second muffler pipe is then positioned into the second muffler chamber, and the second muffler chamber is filled in the same manner as the first muffler chamber. The filling sleeve is then removed from the second muffler pipe.
