Appeal No. 2002-0956
Application 09/182,366
longitudinal displacement of the workpiece disposed thereon (see
page 1 lines 7 through 43).
The British reference discloses a rotary punching machine
comprising an anvil cylinder 34 and a knife cylinder 35 having
blades 37. The cylinders cooperate to punch portions from a
sheet of corrugated board 31 (see Figure 9). The knife cylinder
includes a knockout lever 42 for urging the scrap punched from
the board away from the blades 37 (see page 3, line 129 et seq.).
The German reference discloses a metal cutting cylinder
having a cutter blade 1 and a scraper blade 3, 3'. The scraper
blade functions to wipe lubricating substances and metal particle
debris from the forward surface of the cutter blade after each
cutting operation.
In proposing to combine the foregoing references to reject
claim 1, the examiner concludes that it would have been obvious
at the time the invention was made to a person having ordinary
skill in the art
to utilize a transport belt as taught by Mattison with
the invention of Spengler for the purpose of allowing
for the replacement of damaged cut rubber portions and
decreasing maintenance and lowering costs as well as
providing a surface that prevents inadvertent movement
of the workpiece as the workpiece is [moved] relative
to the tool [answer, page 4],
