Abstract
A machine for accumulating and for stacking a plurality of documents in a first plane so that the leading end of the documents are in a shingled relationship. Upon actuation of a system of first and second pairs of feed rollers, the documents in a stack are fed along a path leading to an angularly disposed, first buckle chute of a folding device. While traveling within the first buckle chute, the first and second pairs of feed rollers cause the leading end of the stack of documents to become aligned in relationship, thereby providing squarely folded groups of documents when the folds are made in a folding device within the machine.
