First claim
Opening claim text (preview).
What is claimed is: 1 . A deflaker plate for a deflaker machine, the deflaker plate comprising: a substrate; and a plurality of teeth extending from the substrate, wherein a specified number of teeth of the plurality of teeth comprises a serrated face. 2 . The deflaker plate of claim 1 , wherein the serrated face comprises a serration pattern having a specified screw thread pitch or a specified linear pitch. 3 . The deflaker plate of claim 1 , wherein the serrated face comprises a curved serration pattern, a circular serration pattern, an angled serration pattern, or a cross-hatched serration pattern. 4 . The deflaker plate of claim 1 , wherein less than an entire portion of the serrated face comprises serrations. 5 . The deflaker plate of claim 1 , wherein the specified number of teeth having the serrated face comprises all of the teeth of the plurality of teeth. 6 . The deflaker plate of claim 1 , wherein the specified number of teeth having the serrated face comprises less than all of the teeth of the plurality of teeth. 7 . The deflaker plate of claim 1 , wherein the substrate is a disk, a ring, or a segment of a disk. 8 . The deflaker plate of claim 1 , wherein the substrate is a cone, segmented cone, stepped cone or a segment of a stepped cone. 9 . The deflaker plate of claim 1 , further comprising a surface hardening treatment applied to the plurality of teeth. 10 . Deflaker plates for a deflaker machine, the deflaker plates comprising: a first deflaker plate comprising: a first substrate; and a first plurality of teeth extending from the first substrate, wherein a first specified number of teeth of the first plurality of teeth comprises a serrated face; and a second deflaker plate comprising: a second substrate; and a second plurality of teeth extending from the second substrate, wherein a second specified number of teeth of the second plurality of teeth comprises a serrated face; and wherein the first plurality of teeth is configured to intermesh with the second plurality of teeth. 11 . The deflaker plates of claim 10 , wherein the serrated face of the first specified number of teeth and the second specified number of teeth comprises a serration pattern having a specified screw thread pitch or a specified linear pitch. 12 . The deflaker plates of claim 10 , wherein the serrated face of the first specified number of teeth and the second specified number of teeth comprises a curved serration pattern, a circular serration pattern, an angled serration pattern, or a cross-hatched serration pattern. 13 . The deflaker plates of claim 10 , wherein less than an entire portion of the serrated face of the first specified number of teeth or the second specified number of teeth comprises serrations. 14 . The deflaker plates of claim 10 , wherein the first specified number of teeth and the second specified number of teeth having the serrated face comprises all the teeth of the first and second plurality of teeth. 15 . The deflaker plates of claim 10 , wherein the first specified number of teeth and the second specified number of teeth having the serrated face comprises less than all of the teeth of the first and second plurality of teeth. 16 . The deflaker plates of claim 10 , wherein the first specified number of teeth having the serrated face comprises all the teeth of the first plurality of teeth, and wherein the second specified number of teeth having the serrated face comprises less than all the teeth of the second plurality of teeth. 17 . The deflaker plates of claim 10 , wherein the first specified number of teeth having the serrated face comprises less than all the teeth of the first plurality of teeth, and wherein the second specified number of teeth having the serrated face comprises all the teeth of the second plurality of teeth. 18 . The deflaker plates of claim 10 , wherein the first substrate and the second substrate are disks, rings, or segments of disks. 19 . The deflaker plates of claim 10 , wherein the first substrate and the second substrate are cones, segmented cones, stepped cones or segments of stepped cones. 20 . The deflaker plates of claim 10 , further comprising a surface hardening treatment applied to the first plurality of teeth or the second plurality of teeth or both the first and second plurality of teeth.
