DEFINITION

Classification: 409/165

Including means to support work for rotation during operation:

(under subclass 163) Apparatus wherein the structure for moving the workpiece toward the cutting tool to effect shaping of the workpiece is provided with means to hold that workpiece against gravity and against the force of the tool while allowing the workpiece to turn continuously about an axis when presented to be shaped by the rotating cutting tool.

(1) Note. Rotation of the work support to cause the periphery of the workpiece to move past the cutting tool is considered to be "infeed" for this subclass.
