Appeal No. 1996-0208
Application 08/098,153
art, as represented by Dowd, includes a single die press means
which is used to shape two or more paper blanks (formed by a
cutter) into shaped paper products (specification, page 4,
lines 15-27 and Dowd, claim 1). In Dowd, the paper blanks are
stacked vertically on one another and the stack is fed into
the single die cavity through a guide means (see figure 1 of
Dowd) thus resulting in a substantial increase in the number
of press formed products produced per cycle and per minute.
According to appellant, the problem with the operation of this
prior art device is that it results in paperboard products of
poor quality which are unsuitable both functionally and
aesthetically (specification, page 4, line 30 to page 5, line
18).
Appellant’s invention involves an improvement to the Dowd
apparatus in that it “retrofits” Dowd’s existing forming
apparatus “having a die set that defines a single cavity with
at least one reciprocating die plate” by installing “at least
one upper die plate and at least one lower die plate in
vertically stacked relationship with respect to the die set of
the existing forming apparatus” thereby providing an
additional die cavity. See step (a) in appealed claim 14.
