Abstract:
A method of manufacturing an exhaust emission control device, comprising:disposing a viscous-elastic material around at least a portion of a substrate to form a wrapped element; inserting the wrapped element in a first end of a stuffing device; placing a second end of the stuffing device adjacent to an open end of the housing; compressing the viscous-elastic material at first compression rate; compressing the viscous-elastic material at a second compression rate that is slower than the first compression rate; and urging the wrapped element through the stuffing device into the open end; wherein the stuffing device comprises a first taper proximate the first end, and a second taper proximate the first taper, the first taper has a larger angle than the second taper, and wherein the second taper has an angle greater or than 0Â°.
