Abstract

Pattern envelopes or like flat articles retained in stack configuration by elements engaging marginal portions of the lead article are withdrawn substantially in such flat condition by displacing the lead article in its entirety in a manner spacing at least one lead article marginal portion from its associated retaining element and then displacing the same outwardly of the stack spacedly from the retaining element. Further outward displacement of the withdrawn marginal portion effects sequential withdrawal of the other marginal portion from the stack.
