摘要： A potter's wheel for forming an oval pottery, such as dish, bowl or the like, has a die (26) for positioning clay to be formed and a revolution-rotation device (24). The revolution-rotation device (24) provides the revolution of the die about a first axis and the rotation of the die about a second axis. A tool is held at a predetermined position with respect to the first axis. While the direction of the rotation is same as that of the revolution, the speed of the rotation is a half of that of the revolution.

摘要： The present invention relates to an apparatus and a method for making products having various shapes. The apparatus is for making a product by shaping or processing work piece using a relative movement between the work piece and a tool. The apparatus is provided with a work piece support on which the work piece is located, a revolution-rotation driving device including a first axis and a second axis in parallel with the first axis and revolving around the first axis, the device revolving the work piece support around the first axis and rotating the work piece support on the second axis; and a tool support for supporting the tool in such a manner that the tool is maintained in a predetermined position with respect to the first axis. The revolution-rotation driving device further includes a revolution-radius adjustment for adjusting a distance between the first axis and the second axis. Further, the revolution-rotation driving device maintains a direction of the revolution of the work piece support and a direction of the rotation of the work piece support in a same direction and allows a ratio of the number of revolution of the work piece support to the number of rotation of the work piece support to be maintained in a constant ratio of n (natural number) : 1.
