Abstract: The barrels orbit to create a centrifugal force on the barrel contents while the barrels are concurrently rotating about internal axes counter to the orbital movement, utilizing endless members to impart both the orbital and counter rotating movement to a plurality of the barrels.
Abstract: The buffing machine of the present invention includes one or more buffing wheels to which workpieces are successively presented on a continuously traveling conveyor wherein the workpieces are rotatably mounted. The axis of workpiece rotation is adjustable to any angle desired relative to the conveyor travel and the axis of a buffing wheel. The angle the axis of rotation of the workpiece makes with the buff wheel axis is selected so that rotation of the buffing wheel imparts a desired speed of rotation of the workpiece.
