Patent ID: 7954482

Claim:
An aging device for aging a stone, comprising: a rotary support operatively connected to a rotary shaft, the rotary support being a disk-shaped plate that is rotated about an axis thereof; at least one abrasive tool mounted to the rotary support for roughing and/or polishing a surface and peripheral edges of the stone when the rotary support is brought into functional contact with said surface and said peripheral edges; biasing means biasingly connecting said at least one abrasive tool to the rotary support, each one of said biasing means having at least a first end and a second end, the first end being fixed to the rotary support and the second end extending away therefrom, the second end bearing at least one of said at least one abrasive tool, the biasing means urging said at least one abrasive tool away from the rotary support while allowing said at least one abrasive tool to move toward the rotary support when the rotary support is brought into functional contact with the surface of the stone, thereby allowing said at least one abrasive tool to follow a surface profile of the stone while roughing and/or polishing the surface of the stone; and a protective plate mounted to the rotary support to substantially shield said biasing means, the protective plate comprising at least one opening through which said at least one abrasive tool is urged by the biasing means.
