Appeal 2006-1578
Application 09/520,032
Claims 20 and 25 illustrate Appellants’ invention of a production tool
for manufacturing an abrasive article, and are representative of the claims on
appeal:
20. A production tool for manufacturing an abrasive article that
comprises a major surface having deployed in fixed position thereon first
and second three-dimensional abrasive composites, each of said composites
comprising abrasive particles dispersed in a binder and having a shape
defined by a substantially distinct and discernible boundary which includes
substantially specific dimensions, wherein said first abrasive composite has
a shape having specific first dimensions and said second abrasive composite
has a shape having second specific dimensions, wherein each of said
abrasive composites has a boundary defined by at least four planar surfaces
wherein adjacent planar surfaces of one composite meet at an edge to define
an angle of intersection therebetween, wherein at least one angle of
intersection of said first abrasive composite is different from all of the angles
of intersection of said second composite, said production tool comprising a
structure having a plurality of adjacent three-dimensional cavities formed on
a major surface thereof, wherein each three-dimensional cavity is defined by
a substantially distinct and discernable boundary which includes
substantially specific dimensions, wherein a first three-dimensional cavity
has a first shape having specific first dimensions and a second three-
dimensional cavity has a second shape having specific second dimensions,
wherein each of said three-dimensional cavities has a boundary defined by at
least four planar surfaces wherein adjacent planar surfaces of one three-
dimensional cavity meet at an edge to define an angle of intersection
therebetween, wherein at least one angle of intersection of said first three-
dimensional cavity is different from all angles of intersection of said second
dimensional cavity, wherein the production tool is a roll, and wherein each
of the cavities has a single opening.
25. A production tool suitable for use in manufacturing an abrasive
article comprising a plurality of cavities, wherein the cavities each have
dimensions defining the cavity, wherein at least 10% of pairs of adjacent
cavities have at least one dimension different between the two cavities of the
pair, and wherein each of the cavities has a single opening.
