.~.~ With actuation of split die
DEFINITION
Classification: 72/357
With actuation of split die:
(under subclass 352) Subject matter including utilization of a work-engaging member constructed in two or more relatively movable parts, separable to admit work and movable to closed position to confine work there between and to afford a shape-imposing surface or cavity adjacent to a portion of the work, said device further comprising a power-transmitting train for moving said parts to closed position.
(1) Note. For this subclass, the multipart work-holding or work-confining member must also constitute a die (i.e., must
comprise a work-shape-imposing, or limiting surface which at some time during the movement of the coacting tool or work forcer is engaged by work), but it must not constitute a die couple. In other words, if parts of the work gripper deform work while closing into gripping engagement therewith, they constitute a tool couple; in combination with the relatively movable header or other tool they thus become a tool complex for subclasses 353.2+, 381+, or 394+.
(2) Note. Usually, but not necessarily, the work gripper die surface defines a closed die cavity; however, the coacting tool may itself constitute the closed die and the gripper die surface may have any form, e.g., flat or segmental.

353.2+, for closed die tool complex wherein two or more tools coact to grip partially deformed work, and see (1) Note above.
