lines 27-30). This teaching of use of a larger number of bores
in the direction perpendicular to the direction of web, together
with the teaching by Landis that the hopper can have various
configurations other than the generally cylindrical configuration
exemplified for two bores (col. 3, lines 54-56), would have
fairly suggested, to one of ordinary skill in the art, forming an
elongated hopper (6) and die (40) in the direction of a row of a
higher number of bores used to form a wider stripe, in order to
accommodate the higher number of bores. Such a person would not
have been led by Landis to enlarge the hopper and die also in the
direction perpendicular to the row of bores, such as by using a
larger cylindrical hopper and die to accommodate a longer row of
bores, because such an enlargement would provide no operational
benefit and would waste hopper and nozzle material.
Claim 18, from which claim 21 depends, requires that the
apertures are longitudinally evenly spaced. Landis’ teaching
that the coating stripe is to have a uniform thickness across its
width (col. 4, lines 55-59) would have fairly suggested, to one
of ordinary skill in the art, making the bores evenly spaced in
order to obtain this uniform thickness.
