and 18-20 is dismissed. This leaves for our consideration on
appeal only claims 1-9, 13-15 and 17 as amended subsequent to
the final rejection. 1
Appellant’s invention relates to a method of fabricating
a reinforced foil coating material with a low frictional
coefficient including contacting an expanded metal sheet (2)
and at least one polytetrafluoroethylene (PTFE) strip (1 or 3)
to form a stack, calendering the stack to at least partially
crush the expanded-metal sheet, and then heating the
calendered stack to sinter the PTFE strip, thereby forming the
foil-type material. During the calendering step, pressure
greater than 200 kg/cm , and preferably approximately 5002
kg/cm , is applied. A copy of representative independent2
1While the amendments filed by appellant on December 30,
1996 (Paper No. 12) and on April 28, 1997 (Paper No. 17) have
been approved for entry by the examiner (see Paper Nos. 13 and
18), they have not as of yet been properly clerically entered.
During any further prosecution of this application before the
examiner, this oversight should be corrected. In addition, in
claims 14, 15 and 17 the spelling of calendering should be
corrected.
