DEFINITION

Classification: 271/256

(under subclass 8.1) Device provided with means to discontinue, suspend or alter the normal flow or travel of sheets from a stack to an operation station.

(1) Note. A distinction should be made between the temporary stopping of a sheet during the period of time necessary to align that sheet, (which temporary stopping is found in the patents of subclasses 226+, as appropriate) and the stopping of the normal travel of a succession of sheets (which latter stopping is found in the patents of this and indented subclasses).

(2) Note. This subclass is for a device wherein a condition of the device itself, or a machine associated with the device is sensed, and feed is interrupted in response thereto.
