(answer, page 10) is inconsistent with both the Wiand ‘795
disclosure and the ordinary and accustomed meaning of the term
“periphery.”
Maran discloses a coated abrasive grinding disc which is
prepared
by coating a substrate disc or sheet of fibrous
paperboard, or like material, as by means of a
patterned adhesive transfer roll, embossing or the
like, to form rows of geometrically patterned
adhesive coated areas in the substrate; and then
applying finely divided abrasive material over the
adhesive coated areas to from a geometrical pattern
of abrasive coated areas on the substrate with rows
of uncoated scavenging channels extending between
the abrasive coated areas and opening onto the outer
or peripheral edge of the abrasive coated disc

Figures 4 through 6 illustrate such an abrasive disc made from
a flat fiberboard sheet, and Figures 11 and 12 show a disc
made from an embossed fiberboard sheet.
In proposing to combine Wiand ‘795 and Maran to reject
the appealed claims, the examiner concludes that it would have
