Abstract
An abrasive plate having an abrasive surface for performing abrading applications is provided. The plate includes a base member having a substantially smooth surface with a plurality of holes formed therethrough. A plurality of pairs of spaced apart slots radiate outwardly from each of the holes to define tab members. The tab members may be selectively raised or deformed to protrude from the smooth surface to collectively form an abrasive surface. The number of tabs raised may be selected to control the coarseness of the surface.
Claims16
An abrasive plate comprising:
- a base member having a substantially smooth surface and defining a plurality of holes through the base member;
- at least one pair of slots formed in the base member adjacent at least one of said holes, each pair of slots and one of said plurality of holes defining a tab, the tab having a distal surface defining at least two abrading edges;
- and
- wherein the tab is inclined relative to the smooth surface of the base member to define an abrasive surface.

An abrasive plate comprising:
- a base member having a plurality of protrusions formed thereon, each protrusion having a body portion having a pair of linear sidewalls and a concave distal end having first and second abrading portions, the abrading portions defining an abrasive surface.
An abrasive plate comprising:
- a base member having a substantially smooth surface defining a plane and a plurality of tab members formed therein;
- wherein at least some of the tab members are inclined with respect to the plane defined by the smooth surface of the base member to define an abrasive surface, and at least some of the tab members lie within the plane parallel to the smooth surface of the base member.
