Abstract
A paper web is maintained on a rotating apertured drum by means of a vacuum created inside of the drum. The paper length is slightly greater than the circumference of the drum thereby providing a tangentially projecting flap which is detected by a flap sensor. The concurrance of a pulse from the flap sensor with an end of message signal enables a counter. A first series of selected states of the counter are decoded and used to interrupt the vacuum causing the paper to come to rest against a shroud surrounding the drum. A second series of counter states, some of which coincide with the first series, open a discharge door covering a paper discharge opening in the shroud. When the vacuum is reapplied to the drum, upon expiration of the first series of counter states, the rotating drum boosts the paper out through the discharge opening.
