1990). The appellant has made no such showing. Indeed, the
appellant's
disclosure (see specification page 7) fails to attach any
particular significance to the tension range in question.
In the same vein, Dischler's comprehensive description of
the type of textile materials which may be treated by the
method disclosed therein would have suggested using the method
to treat crease sensitive webs as broadly recited in claims 1
and 7, including those further defined in claim 7 as having a
ratio of tensile stiffness to bending stiffness of greater
than 0.5 CM .-2
As for the limitations in claims 1 and 7 requiring that
the stream of gaseous fluid be projected against the web in
the direction of travel of the web, Dischler does indicate
that gaseous fluid is projected against the web opposite the
direction of travel in the preferred form of the method.
Dischler recognizes, however, that the effect of the treatment
on the web may be varied by changing the impingement direction
of the gaseous fluid. Furthermore, Sack teaches that the same
sort of web treatment (e.g., to improve the softness and hand
