Abstract

To prepare an absorption muffler for motor vehicles with a sound-absorbing material arranged in a hollow space of an exhaust muffler body in the form of glass wool (2), which is introduced into the hollow space in the form of an expanded, endless glass fiber roving, it is proposed that the exhaust muffler body (1) be completely prefabricated and assembled before the glass wool (2) is introduced into the prefabricated, assembled exhaust muffler body (1) from the outside.
