An accumulator apparatus for paper collations having an accumulation chamber for receiving sheet material, the chamber defined by a fixed guide on one side, a movable guide on the other side and a movable stop member at one end. Rollers are included for driving the sheet material against the stop member, and gates are provided for moving the movable guide between a first position in which it is spaced from the fixed guide by a gap sufficiently small to prevent buckling of the sheet material as it is driven by the rollers against the stop member, and a second position in which the movable guide is spaced away from the fixed guide for discharge of the sheet material from the chamber.
