  • Patent number: 7954482
    Abstract: The present invention provides an apparatus and a method for aging a stone, preferably an artificial stone. The aging device comprises a rotary support operatively connected to a rotary shaft, at least one abrasive tool mounted to the rotary support for roughing and/or polishing a surface of the artificial stone when the rotary support is brought into functional contact with said surface, and biasing means that biasingly connect the abrasive tool to the rotary support. The biasing means urge the abrasive tool away from the rotary support while allowing the same to move toward the rotary support when the rotary support is brought into functional contact with the surface of the artificial stone, thereby allowing the abrasive tool to follow a surface profile of the artificial stone while roughing and/or polishing its surface.

  • Publication number: 20080078047
    Abstract: A rotary buffer for buffing and polishing concave surfaces. The rotary buffer includes a malleable cone, a cone shaft, and a mounting shaft. The mounting shaft is configured to be received in a chuck of a rotary power tool. The cone and cone shaft work in conjunction with one another to absorb impact from a surface being buffed and polished and to prevent the rotary buffer from bouncing.

  • Publication number: 20020174503
    Abstract: A finishing unit for a vehicle surface treatment apparatus composed of a thin sheet-like pad of material having flexible characteristics, the pad being adapted for contact with a vehicle surface. A buffer member of flexible material is also provided and opposes a surface area on the pad. A stiffening structure is oriented over a majority of the opposing surface areas of the buffer member and the pad to effect a fixed securement of the opposing surface areas together so as to provide an area of substantially less flexibility than the individual flexibility characteristic of each of the buffer member and the pad.
