Abstract
A wire mesh rivet (13) is provided which is used to produce a wire mesh isolator (11) in a bore (9) of a substrate such as a heat shield (7) for a vehicle exhaust system. The rivet (13) comprises a unitary wire mesh structure (19) which has a collar (15) and a shank (17). The collar (15) has a higher density than the shank (17), e.g., the collar (15) has the density of the finished isolator (11). The rivet (13) is formed into the finished isolator (11) by compressing the shank (17) to form a second collar, while restraining the original collar (15) from substantially changing its shape. The rivet (13) can include a metal insert (23) which prevents the wire mesh of the finished isolator (11) from experiencing high levels of compression when the substrate is fastened to its supporting structure. The rivets (13) can be carried by a dispensing strip (31) and can be formed into the finished isolator (11) using forming equipment (39) whose dimensions are compatible with the limited space available with some substrates.
