Patent

CA 2566854

The present invention provides an abrasive material comprising a base surface having a plurality of pyramidal shapes protruding therefrom the base surface and the protrusions being formed of the same material, each protrusion having a substantially triangular, square, or polygonal base and triangular sides which meet at an apex which substantially forms a point. The pyramidal shapes have apexes in at least two distinct planes with a portion of the pyramidal shapes extending further from the base surface than others, with the apexes of the protrusions providing intermixing cutting and planning edges in a pattern such that the material is capable of abrading independent of direction of use.

L'invention porte sur un matériau abrasif comprenant une surface de base dotée d'une pluralité de formes pyramidales protubérantes, la surface de base et les protubérances étant formées du même matériau, chaque protubérance présentant une base sensiblement triangulaire, carrée ou polygonale et des côtés triangulaires qui se rejoignent au niveau d'une extrémité formant presque un point. Les formes pyramidales sont dotées d'extrémités selon au moins deux plans distincts, une partie des formes pyramidales s'étendant plus loin de la surface de base que les autres, les extrémités des protubérances offrant des rebords à la fois tranchants et ordonnés selon un schéma tel que le matériau puisse abraser dans n'importe quel sens d'utilisation.
