A loose fiber packing material for a muffler of an internal combustion engine is temporarily confined in a transfer cartridge, having a shape which is substantially complementary or somewhat smaller than the muffler cavity. The transfer cartridge is adapted to receive a pushing device for discharging the loose fiber packing material from the transfer cartridge into the muffler cavity during manufacture of the muffler. The transfer cartridge allows loose fiber packing to be prepacked, shipped and directly transferred to a muffler cavity without the use of molding resins or packaging materials which would otherwise be inserted into the muffler along with the loose fiber packing material and burned away during initial use of the muffler, causing undesirable smoke and odor.

[ What is claimed is:] [1.] In combination, a transfer cartridge and a muffler having a cavity of predetermined size and shape, said transfer cartridge comprising:a pair of coextensive inner and outer casings;an end wall on the casings; and,a predetermined quantity of loose fiber packing material between the casings;said casings and end wall together defining a cavity of predetermined size and shape, said loose fiber packing being at least partly confined in said cavity, said cavity having a discharge opening for discharging the loose fiber packing material from said cavity, said end wall further including at least one opening adapted to receive a pushing device for discharging said loose fiber packing material from said discharge opening,wherein the cavity of the transfer cartridge is substantially complementary to the muffler cavity and the loose fiber packing is transferable from the transfer cartridge to the muffler cavity.
