Abstract
A method for filling a muffler shell with a fibrous material includes providing an outer muffler shell, applying a temporary form to the outer shell to define a muffler chamber within the outer muffler shell, and wetting the fibrous material by forcing moisturized compressed air into contact with the fibrous material. The wetted fibrous material is inserted into the muffler chamber, and the temporary form is removed from the outer muffler shell.
Claims29
A method for filling a muffler shell with a fibrous material comprising the steps of:
- (a) providing an outer muffler shell;
- (b) applying a temporary form to the outer shell to define a muffler chamber within the outer muffler shell;
- (c) wetting the fibrous material by forcing moisturized compressed air into contact with the fibrous material;
- (d) inserting the wetted fibrous material into the muffler chamber;
- and
- (e) removing the temporary form from the outer muffler shell.
A method for filling a muffler shell with a fibrous material comprising the steps of:
- (a) providing an outer muffler shell having at least one muffler chamber defined within the outer muffler shell;
- (b) wetting the fibrous material by forcing moisturized compressed air into contact with the fibrous material;
- and
- (c) inserting the wetted fibrous material into the muffler chamber.
A method for filling a muffler shell with a fibrous material comprising the steps of:
- (a) providing a muffler shell having a lower outer shell;
- (b) applying a temporary form to the lower outer shell to define a muffler chamber within the lower outer shell;
- (c) texturizing the fibrous material by forcing compressed air through the fibrous material;
- (d) wetting the texturized fibrous material by applying water to the texturized fibrous material;
- (e) inserting the texturized and wetted fibrous material into the enclosed muffler chamber;
- and
- (f) removing the temporary form from the lower outer shell.
A method for filling a muffler shell with a fibrous material comprising the steps of:
- (a) providing a muffler shell having a lower outer shell;
- (b) applying a temporary form to the lower outer shell to define a muffler chamber within the lower outer shell;
- (c) simultaneously texturizing and wetting the fibrous material by forcing moisturized compressed air into contact with the fibrous material;
- (d) inserting the wetted fibrous material into the muffler chamber;
- and
- (e) removing the temporary form from the lower outer shell.
