DEFINITION

Classification: 72/399

Concurrently actuated tools:

(under subclass 394) Device comprising means so interconnecting the tool-moving or -guiding means as to cause or assure simultaneous movement of the movable tools.

(1) Note. The tools are not required to be moved in exact synchronism to meet the definition of this subclass; but their cycles of motion must overlap, to distinguish from the sequentially driven or manipulated tools of subclass 403.

187+, for metal deformation by concurrent actuation of "flying" tools.

199+, for a closed-die tool-complex with concurrently actuated tools.

353.2+, for a closed-die tool-complex with concurrently actuated tools.

383, for concurrently actuated tools in an offset-face tool-complex. 393, for concurrently actuated receding tools (e.g., for stretching or flaring work).
