Patent ID: 7670275

Claim:
A paper scoring system, including: a cylindrical first roller rotatable on a first axis and having a circumferential tool-retaining groove with an axial first width; a flexible scoring tool comprising an annular base having an axial base width adapted for a nesting engagement in the tool-retaining groove to removably secure the scoring tool for rotation with the first roller, and an annular scoring feature projecting radially outward from the base, the scoring feature having a radial scoring feature height and an axial scoring feature width, wherein the scoring feature width is less than the base width and substantially uniform over a majority of the scoring feature height; and a cylindrical second roller rotatable on a second axis and having a circumferential tool-receiving groove with an axial second width greater than the scoring feature width; wherein the first and second rollers are positionable in a working configuration in which the first and second rollers are axially aligned in spaced apart relation and the first and second axes are substantially parallel, whereby the scoring feature extends into the tool-receiving groove.
