Abstract
A buffing pad assembly having a buffing pad, an attachment means, and an insert (e.g., plastic ring) is provided. In one embodiment, a channel is cut into a side of the buffing pad, creating first and second side portions. The attachment means is then affixed (glued) to a back surface of the buffing pad and the insert is centered on an upper surface of the attachment means. The insert is then heated, affixing it to the upper surface of the attachment means. The insert is then deformed (while it is still pliable) into an L-shape, forming a cavity on the backside of the buffing pad assembly. And because the insert is affixed to the attachment means, and the attachment means is affixed to the buffing pad, deforming the insert results in deforming the back surface of the buffing pad, while maintaining a flat front surface.
Claims20
A buffing pad assembly, comprising:
- a buffing pad having a front surface, a back surface, and a side surface connecting said front surface to said back surface, said front surface being configured to at least one of buff and polish a vehicle, and said side surface comprises an upper side surface adjacent said back surface and a lower side surface adjacent said front surface;
- an attachment means having an inner surface and an outer surface, wherein said inner surface is affixed to said back surface of said buffing pad and said outer surface is configured to connect said buffing pad assembly to a rotary portion of at least one of a rotary and orbital machine;
- and
- a plastic material affixed to a portion of said outer surface of said attachment means, wherein said plastic material is curved upward, resulting in a portion of said attachment means and said upper side of said side surface being curved upward, thereby creating a cavity on a backside of said buffing pad assembly for accepting at least said rotating portion of said at least one of said rotary and orbital machine;
- wherein said buffing pad is substantially circular and said plastic material comprises a plastic ring so that said backside of said buffing pad assembly only has plastic around its edges and not its center where said attachment means comes into contact with said rotating portion of said at least one of said rotary and orbital machine.

A buffing pad assembly, comprising:
- a buffing pad having a front surface, a back surface, and a side surface connecting said front surface to said back surface, said front surface being configured to at least one of buff and polish a vehicle, and said side surface comprises an upper side surface adjacent said back surface and a lower side surface adjacent said front surface;
- an attachment means having an inner surface and an outer surface, wherein said inner surface is affixed to said back surface of said buffing pad and said outer surface is configured to connect said buffing pad assembly to a rotary portion of at least one of a rotary and orbital machine;
- and
- a plastic material affixed to a portion of said outer surface of said attachment means, wherein said plastic material is curved upward, resulting in a portion of said attachment means and said upper side of said side surface being curved upward, thereby creating a cavity on a backside of said buffing pad assembly for accepting at least said rotating portion of said at least one of said rotary and orbital machine;
- wherein said plastic material is affixed to said portion of said outer surface of said attachment means via heat, thereby melting said plastic material to said portion of said outer surface of said attachment means;
- and
- wherein a diameter of said attachment means is less than both (i) a diameter of said back surface of said buffing pad and (ii) a diameter of said plastic material, thereby resulting in said plastic material being affixed to both (a) said portion of said outer surface of said attachment means and (b) a portion of said back surface of said buffing pad.

A buffing pad assembly, comprising:
- a substantially cylindrical buffing pad having a front surface, a back surface, and a side surface connecting said front surface to said back surface, said front surface being configured to at least one of buff and polish a vehicle, and said side surface comprises an upper side surface adjacent said back surface and a lower side surface adjacent said front surface;
- an attachment means having an inner surface and an outer surface, wherein said inner surface is affixed to said back surface of said buffing pad and said outer surface is configured to connect said buffing pad assembly to a rotary portion of at least one of a rotary and orbital machine, said attachment means comprising at least a portion of a hook-and-pile fastener;
- and
- a substantially cylindrical plastic ring affixed to at least a portion of said outer surface of said attachment means so that said backside of said buffing pad assembly only has plastic around its edges and not its center where said attachment means comes into contact with said rotating portion of said at least one of said rotary and orbital machine, wherein a portion of said plastic ring is curved upward, resulting in a curvature upward of a portion of said attachment means and said upper side of said side surface, thereby creating a cavity on a backside of said buffing pad assembly for receiving said rotary portion of at least one of a rotary and orbital machine.
