DEFINITION

Classification: 271/264

(under subclass 8.1) Device provided with means for moving individual sheets to a particular position.

(1) Note. See the glossary entry for "conveyor" in the Class Definition wherein the difference between a "conveyor" of this class (271) and a conveyor of other classes is discussed. It should be emphasized that in a typical patent for this class (271) and this group of subclasses (264+) the total disclosure of the patent and the environment in which the device is to be used is of importance in proper placement of the patent. Thus, although a typical claim of a patent in this and indented subclasses may recite only a conveyor

structure, it is clear from the patent that the conveyor is feeding a sheet to an operation that will change the characteristics of the sheet, or is feeding a sheet that originated from a stack of sheets, or both. In other words, the device does more than move an article from one location to another.
