DEFINITION

Classification: 72/429

WITH MEANS TO DRIVE TOOL:

(under the class definition) Apparatus provided with means to move a movable tool toward work, or toward a cooperating tool, while deformation occurs as disclosed.

(1) Note. For original placement of patents into this or indented subclasses, the following criteria should be applied: (a) "Drive" is tool movement toward the work for deformation of the work; (b) "Retraction" (i.e., tool movement away from the work) and other tool movements (e.g., to adjust the tool position relative to the work or another tool) are provided for only if tool drive is also claimed.
