Abstract: An automatic system for arranging stacks of tortillas, first into rows, and then into a single file. The stacks of tortillas emerge at random from a stacker in a baking line or lines and are formed successively into a row, and then into a file of uniformly spaced stacks in a direction normal to the baking line or lines for travel into a packaging machine.

Abstract: A device as described for unstacking thin, flat articles, particularly flexible articles, and especially tortillas, from a stack of the same, which includes means for repetitively picking up the topmost tortilla in a stack and conveying it to a moving belt where it is deposited individually and separately and moved to a further processing operation. The pick up means includes a rotating cylinder having holes in its surface through which suction acts on the tortillas, to temporarily hold them to the cylinder, and belts around and rotating with the cylinder which transfer the tortillas from the cylinder to the moving conveyor.
