A process is provided for filling a muffler with fibrous material as well as a muffler filled with fibrous material. The process includes a first step of providing a muffler comprising a closed outer shell having an inner cavity and a perforated pipe. The perforated pipe has a first end portion with at least one fill opening. A second step comprises feeding fibrous material into the outer shell inner cavity through the at least one fill opening in the perforated pipe to form a fibrous product in the outer shell.

A process for applying a cushioning material around a substrate, that is a catalytic converter or a muffler, includes rotating the substrate, and winding a strand of fibers around an outer surface of the rotating substrate.

A nozzle for delivering texturized fibrous material into a chamber of a muffler has a body including a texturized fibrous material passageway and a separate directional jet passageway. A method of filling a chamber of a muffler with texturized fibrous material includes the steps of extending a wand into the muffler so that a nozzle on the wand is received in the chamber, discharging a stream of texturized fibrous material into the chamber from a first passageway of the nozzle and discharging a directional jet into the stream of texturized fibrous material from a second passageway of a nozzle whereby the stream of texturized fibrous material is redirected into a desired filling direction to more efficiently fill the chamber.

A method for forming odd-shaped mufflers is achieved by first introducing an unfilled muffler insert having a desired number of pipes and partitions within a two-piece shaped tool. Fibrous material is introduced within desired compartments formed between the shaped tool and unfilled insert to form a filled insert. The shaped tool and filled insert are then placed on a winding device. A yarn thread is then wound and secured around the fibrous material within a gap created between the two pieces of the shaped tool. The winding device and shaped tool are then removed from the filled and wound muffler insert. The wound and filled muffler insert may then either be pressed into a previously formed muffler shell, or alternatively, the muffler shell may be formed around the wound and filled muffler insert to form the muffler.
