Appeal No. 2005-1348
Application No. 09/534,466
The examiner contends that, in Jurkewitz, at the end of a
printing job when the web is running at a very slight speed,
before it stops, printing does not take place and the web tension
is lowered. The examiner further asserts, at page 7 of the
answer, that it is clear, in Jurkewitz, that
printing takes place when the web reaches speed S1.
During the web run up period before it reaches speed S1
from S0, the web is running through the press but is
not being printed. Therefore, when the web is running
through the press from speeds S0 to S1 or after the
printing operation from S1 to S0, the printing press is
in a white web mode since printing does not take place.
Appellants argue that the increase in tension in the instant
invention is independent of press speed and that while Jurkewitz
may teach increasing and decreasing infeed tension, it teaches
these changes in tension as being responsive to speed. In
contrast, the instant claims require the infeed tension to be
increased and decreased responsive to a signal indicating a
change to/from a printing mode from/to a white web mode.
We find for appellants.
In reviewing the reference, as well as the arguments of
appellants and the examiner, contrary to the examiner’s position,
we find nothing in Jurkewitz indicating or suggesting that the
printing press is not printing at very low speeds, e.g., near S0.
