housing, the pollution control element having an inlet, an
outlet, and a face; and
(c) a sheet of mounting material having opposing mating
edges, the sheet of mounting material positioned around a
majority of the face of the pollution control element between
the pollution control element and the housing such that at
least a portion of the mating edges meet to form a seam that
is at a non-perpendicular angle to the inlet and the outlet
of the pollution control element, the seam extends from a
point near the inlet to a point near the outlet of the
pollution control element, and the sheet of mounting material
is capable of being adjusted to variations in the
circumference of the element by moving the mating edges in
opposing directions until the sheet of mounting material fits
tightly about the face of the pollution control element to
prevent exhaust gases from flowing between the pollution
control element and housing.
7. A mounting mat for wrapping a pollution control
element of a pollution control device, the mat comprising a
sheet of mounting material having opposing lateral edges
substantially parallel to each other, and opposing end edges
substantially parallel to each other, and each of the
opposing end edges being at a non-perpendicular angle to the
lateral edges, wherein the mat has a surface area sufficient
to cover and protect the pollution control element from shock
and vibration damage.
