A paper shredder cutting assembly having an arbor, spaced-apart cutting blades on the arbor, a rigid frame set apart from and parallel to the arbor, and braces coupling the arbor to the frame. Each resilient brace is a spacer between a pair of spaced-apart cutting blades. The braces support arbor and cutting blades. The rigid frame and the braces cooperate to strengthen, and to reduce translational motion of the arbor, while allowing rotation of the arbor. Each brace has a brace body, a brace tang extending therefrom, and a brace tab extending perpendicularly from the brace tang. Each brace tab is aligned with another along an edge of the rigid frame, the brace bodies are spacers between the cutting blades, and the brace tabs impair translational motion of the brace bodies. A paper shredder with a motor, gearing, and counterposing cutting assemblies has motion-limited resilient spacers adjacent to cutting blades. |

1. A shredder cutting assembly, comprising:
an arbor; a plurality of spaced-apart cutting blades disposed on the arbor; a rigid frame set apart from and parallel to the arbor; and a plurality of braces coupling the arbor to the frame, each of the braces being disposed as a spacer adjacent to a respective pair of the plurality of spaced-apart cutting blades, wherein the plurality of braces support the arbor; wherein each of the plurality of braces has a positioning device that is disposed parallel to the arbor and that generally restricts translational motion in the arbor when in contact with an adjacent brace, and wherein the rigid frame and the plurality of braces cooperate to strengthen the arbor, while allowing rotation of the arbor. |
