Appeal No. 2001-0159
Application 08/936,724
THE INVENTION
The appellants’ claimed invention is directed toward a
synthetic resin-covered heat insulating/sound absorbing inorganic
fiber mat. Claim 1 is illustrative:
1. A synthetic resin film covered heat insulating/sound
absorbing material of inorganic fibers which comprises:
an inorganic fiber mat, having longer and shorter sides and
two synthetic resin films which cover front and rear surfaces and
both side surfaces along the direction of the longer side of the
inorganic fiber mat, wherein the synthetic resin film at the
front side and the synthetic resin film at the rear side, along
the direction of the longer side of the mat, respectively have
extensions which extend by 10 mm to 200 mm from both sides along
the direction of the shorter side of the inorganic fiber mat,
transverse to the direction of the longer side of the mat, and
which are bonded with a hot melt adhesive at mutually opposing
portions so that both end surfaces along the shorter side of the
inorganic fiber mat are covered with the synthetic resin films,
and the inorganic fiber mat is bonded to one of the synthetic
resin films and the synthetic resin films are mutually bonded in
a discontinuous manner in the direction of the shorter side of
the inorganic fiber mat so that air communicates through unbonded
portions of the synthetic resin films, and further extensions
extending from both sides along the direction of the longer sides
of the inorganic mat.
