DEFINITION

Classification: 271/287

Of successive sheets to plural receivers in succession:

(under subclass 279) Apparatus wherein the sheets to be delivered comprise a sequence of two or more sheets that are being conveyed one after the other toward two or more receivers, the apparatus being provided with means for diverting a first of said sheets into a first receiver, a second of said sheets into a second receiver, the sequence continuing until a sheet is diverted into the last receiver whereupon the next sheet is diverted into the first receiver and the operation is repeated.

(1) Note. A machine for this subclass and the indented subclasses differs from a machine for Class 270, subclasses 58.01+ in that this and the indented subclasses provide for the stacking into plural receivers of sheets from a single or an undetermined source, whereas Class 270, subclasses 58.01+ provides for the stacking into plural receivers of sheets from a plurality of source stacks, the sheets of which are to be collated into a plurality of finished stacks. See the search class notes in the class definition of Class 271 for further discussion. In this and the indented subclasses will also be found a machine which is programmed so that one or more of the receivers is "skipped" to form special stacks.
