Abstract: A series of flat articles are advanced along a path at regular intervals and are folded by continuously traveling fingers which engage an article intermediate its ends and fold the same. The fingers advance the articles to a station at which the folded articles are deposited as the fingers automatically withdraw from the folds. The folded articles may be abutted seriatim into a stack within an accumulator in the form of a conveyor traveling a speed considerably slower than the speed of the traveling fingers.
