DEFINITION

Classification: 53/344

(under subclass 342) Apparatus wherein a closure conforming or shaping member comprises two or more elements.

(1) Note. The individual elements constituting the closure shaping member may act independent of each other or together as a unit.

(2) Note. The subclasses indented hereunder are subdivided

on the basis of the mechanical movement or actuation necessary to effect closure conforming or shaping. Similar apparatus which serves to merely release the die sections after conforming of the closure member involves a search of all the subclasses indented hereunder.

330, for sectional dies used to conform inserted closure members.

334, for sectional dies that rotate during closure conforming. SEE OR SEARCH CLASS

72, Metal Deforming,

279, Chucks or Sockets, appropriate subclasses for segmental gripping devices.

31+, for roller die seaming means.

451, Abrading,

487, for a carrier for a radially movable abrading tool.
