inflation channel near one edge of the material, rows of chambers
extending across the material, flow passageways interconnecting
the chambers in each of the rows, and inlet passageways extending
between the inflation channel and one of the chambers in each of
the rows;
a pair of spaced apart, horizontally extending rollers on
which the roll of film material rests;
an air injector which is connected to a source of air,
positioned below the rollers, and extends in an upward direction
for injecting air into the inflation channel and chambers to
inflate the cushions;
a sealing unit for forming a longitudinally extending seal
across the inlet passageways after the cushions are inflated; and
means for feeding the film material in a generally downward
direction from the roll past the inflation tube and the sealing
unit.
The examiner relies upon the following references as

Appellants' claimed invention is directed to an apparatus
for inflating and sealing air-filled packing cushions. The
apparatus comprises a pair of spaced apart, horizontally
extending rollers for supporting a roll of film having two layers
that are sealed together, an air injector positioned below the
rollers for injecting air into the inflation channel formed by
the two layers, and means for feeding the film from the pair of
