DEFINITION

Classification: 72/20.2

To control predetermined sequence of operating movements (e.g., of one tool operating on work):

(under subclass 20.1) Subject matter including regulating the succession of function or movement of one or more operating assemblages.

(1) Note. The term "operating assemblage", is intended to include a tool, or any element or group of elements, acting together, which performs an action or produces an effect upon the work or product; or which causes a tool movement necessary to deformation of the work; or which is ancillary to a deforming instrumentality.

(2) Note. This subclass is the locus of patents disclosing control of a sequence of operations or movements of a single operating assemblage. For example, a disclosure wherein a tool advances toward and retracts from the work, under control of switches positioned at the limits of travel of the tool, would be placed herein. See subclasses below for control of different mechanisms.

13.5+, for sensing a tool or tool-linked part to control a predetermined sequence of operating movements in metal deforming by use of a roller or roller-like tool.
