Appeal No. 1998-0514
Application 08/523,907
“b”, cutters formed of a material having a heat expansion
coefficient “c”, and counterweights formed of a material
having a predetermined heat expansion coefficient “d”, wherein
the relationship between the heat expansion coefficients is
such that both “c” and “b” are greater than both “a” and “d”.
German ‘516 does not disclose that the cutter holders are
formed of composite fiber material, or that the heat expansion
coefficients of the cutters, cutter holders, cutter cylinders,
and counterweights are such that the heat expansion
coefficients of both the cutters and cutter holders are
greater than the heat expansion coefficients of both the
cutter cylinders and the counterweights.
For the reasons discussed above, we view Gomi as
suggesting, at best, that the cutter cylinders of German ‘516
should be constructed in accordance with Gomi’s teachings to
provide for improved rigidity of the cutter cylinders. We
find no suggestion whatsoever in the combined teachings of the
applied references that the cutter holders of German ‘516
should be formed of composite fiber material, or that the heat
expansion coefficients of the cutters, cutter holders, cutter
cylinders, and counterweights should be selected to provide
