ABSTRACT:
Control apparatus enable the selective injection of individual sheets from channels one or two to collate and combine a stream of sheets in a selected presentation of East/West or West/East mixed multiple forms using both channels one and two to process one particular form, effectively zig-zagging from one channel to the other, and also adapted to control and inject North/South mixed multiples in which all the pages for one form in one channel, but both channels must be controlled to be sure multiple forms from one channel are not processed out of order relative to the other channel. A dual registering stacking interface stages, registers, transports, justifies and stacks forms in which forms are delivered to a side-by-side holding areas known as channels one and two, where they are held stationary and accumulate in a stack or continue feeding as separate forms.
