DEFINITION

Classification: 198/405

(under subclass 404) Apparatus wherein the conveyor comprises an endlessly-orbiting surface that travels in the direction of the "X" axis and extends transversely of said direction

along a "Z" axis, and wherein as a particular "Z" axis line moves along the "X" axis, the "Z" axis turns about the "X" axis, thereby turning the article supported and carried by the surface.

(1) Note. The terms "X" axis and "Z" axis are defined and further discussed in (2) Note of subclass 373.

(2) Note. Usually the conveyor comprises two belts cooperating together to frictionally maintain a conveyed article between them and both belts twist together.
