DEFINITION

Classification: 52/763

Interkeyed edge configurations of adjacent facers cooperate with shaft:

(under subclass 474) Structure wherein edge-to-edge related facers have interfitting edge configurations (e.g., edges of tongue and groove type, or edges oblique to major faces of the facers), which configurations cooperate with the sustainer.

(1) Note. The term "interfitting" does not require contact between the edge configurations.
