Abstract: In order to make utmost use of the time and effort of an operator, a duplication system has been devised in which first the duplicator equipment feeds the copy paper along a linear path while producing the copies, the path then turns, and the copy is fed by a direction changing means in a direction substantially normal to the original path into a sheet distributor which has its unloading apertures arranged so as to be convenient to an operator standing at an operator station beside the discharge end of the duplicator device at the operation side thereof. The distributor is of a type such that the unloading openings are exposed to operator access at or slightly above waist level, and is preferably a rotary distributor capable of moving the filled pockets to a fixed unloading position.

Abstract: A conveyor is provided for accepting sheets moving in one direction from a duplicator and conveying them at an angle to the initial direction; e.g., 90.degree.. The conveyor consists of rollers of relatively large diameter arranged with close spacing so that sheets of paper will pass easily from one to the other, and entering sheets will find fairly continuous support whatever their size. The rollers are set at an angle to the desired feed path to provide an effect urging the sheets towards a side alignment stop and the construction is such that the angular roller setting may be readily made during manufacture, to act towards whichever side of the feed path is selected as the one to carry the alignment stop surface.

Abstract: Duplicating equipment is provided for printing on both faces of the same sheet or, in the alternative, making two impressions on the same face (e.g., in different colors) by means of two printing heads. Both printing heads are served with masters from a single supply point, the masters being fed in proper order and attached to the master cylinder of the appropriate printing head automatically. In one form of the invention, the single master supply point takes the form of a single master maker and converter.
