Abstract

A sheet handling means is provided for use with a duplicating machine. A duplicator is provided having first and second printing couples for printing first on one face of a copy sheet and then on the other and whose paper feed paths are arranged substantially normal to each other. The duplicator also includes special sheet handling means for passing the copy sheet from the first to the second printing couple and also inverting the sheet. The copy sheet is advanced in a first path and direction away from the first printing couple and is advanced in a second path substantially normal to the first path in a second direction towards the second printing couple. The sheet handling means comprises a sheet turn-over device positioned to intersect the copy sheet paths for receiving and progressively inverting the copy sheet as it is advanced in the first path and simultaneously directing the sheet from the first to the second path.
