Abstract

In some copiers and duplicators it is necessary to invert copy sheets. A tri-roll inverter apparatus is shown in the figure that will accomplish sheet inversion independent of copy sheet size, properties, condition or machine configuration. In operation of the inverter apparatus as shown in the figure, a sheet is fed into nip A-B of inverter 20. A sensor 50 senses when the sheet leaves the nip and sends a signal which actuates solenoid 30. The actuated solenoid forces movement of a constantly rotating scuffer roll 40 into contact with the sheet to thereby drive the sheet into output nip B-C. The solenoid is deactuated by conventional means once the sheet is under the influence of output nip B-C thereby allowing scuffer roll 40 to assume its original position. Another feature of this inverter is its capability of simultaneous sheet inversion.
