Patent ID: 8109262

Claim:
An aging device for aging a stone, comprising: a rotary support operatively connected to a rotary shaft, the rotary support being a cylinder that is rotated about a longitudinal axis thereof; at least one abrasive tool mounted to a circumferential surface of 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 the surface and the peripheral edges; and biasing means biasingly connecting the at least one abrasive tool to the rotary support, each one of the biasing means comprising a rigid biasing arm having a first arm end and a second arm end, the first arm end being connected to a suspension unit mounted to the rotary support and the second arm end being a free end extending away from the rotary support and bearing at least one of the at least one abrasive tool, the biasing means urging the at least one abrasive tool away from the rotary support while allowing the 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 the at least one abrasive tool to follow a surface profile of the stone while roughing and/or polishing the surface of the stone.
