Appeal No. 2001-0112
Application No. 08/486,494
Tukihara, the alleged anticipatory reference, is directed to
a rod and method of manufacturing the same. The object of
Tukihara is to provide a rod which has appropriate degrees of
flexibility and rigidity throughout its length (column 1, lines
48-53). This is achieved
by the feature that a prepreg tape is wound to have
adjacent winds partly overlapping each other in a tip
end region of the rod, and spaced from each other
axially of the rod in a butt end region of the rod.
[Column 1, lines 55-58.]
Tukihara discloses a number of embodiments of the invention
for accomplishing the stated objective. These include a Figures
1-3 embodiment (column 2, line 67, through column 3, line 16)
wherein first a prepreg sheet 6 having reinforcing fibers
oriented axially of the rod and having a width extending over the
length of the rod is wound on a mandrel 4, whereafter a prepreg
tape 5 having reinforced fibers oriented longitudinally thereof
is wound on the mandrel, and wherein the tape is wound such that
its winding partly overlap each other at the tip end of the rod
and are spaced from each other at the opposite end of the rod.
Also disclosed is a Figures 4(a)-4(b) embodiment (column 3, lines
27-31) wherein a prepreg tape 5’ is wound on the mandrel prior to
prepreg sheet 6, a Figures 5(a)-5(b) embodiment wherein prepreg
sheets 6a and 6b having reinforcing fibers laid out on the bias
