Application No. 09/571,606
a cylinder body with an outer surface,
a set of tucking blades, the set of tucking blades
being spaced axially apart from each other,
a grid-shaped expansion plate adjustable to change
an effective diameter of the folding cylinder, the
expansion plate having a first plurality of apertures
spaced axially next to each other and a second
plurality of apertures spaced axially next to each
other and circumferentially spaced from the first
plurality of apertures, the set of tucking blades
fitting through the first plurality of apertures during
a tucking operation so as to present a fold in a
signature to the two fold rollers.
The examiner relies upon the following references as
evidence of obviousness:

Appellants' claimed invention is directed to a rotary blade
folder of a printing press in which a continuous web is cut into
signatures and folded. The rotary blade folder comprises a
folding cylinder which in turn comprises an adjustable grid-
shaped expansion plate having a first and second plurality of
apertures. The first plurality of apertures is spaced axially
next to each other, as is the second plurality of apertures. The
first and second plurality of apertures are circumferentially
spaced from each other. A set of tucking blades fits through the
first plurality of apertures so as to present a fold in the web,
