Accumulator and stacker for sandwiched cookies, biscuits and like articles in which two side-by-side rows of sandwiched cookies are delivered from a conventional sandwiching machine and stacked one sandwich on top of another sandwich in an adjacent row and then accumulated into individual two high stacks with the stacks in tandem groups of two, three, four or more stacks at the in-feed conveyor of a conventional horizontal wrapping machine. The sandwiched cookies may be round, square and elongated rectangular cookies or of various similar shapes. The accumulator is between the discharge end of the sandwiching machine and the intake end of a wrapping machine, and provides a continuous high speed stacker supplying pre-selected stacked groups of sandwiches to the infeed conveyor of the wrapping machine in a continuous path. The transitions from the sandwiching machine to the stacker and accumulator and the stacking and accumulating and feeding of the accumulated groups to the wrapping machine are smooth and gradual, making it possible to handle rectangular cookies in a cross-wise orientation without crumbling of the cookies or other damage thereto. This is all attained by a series of overhead conveyors cooperating with the sandwiching machine and wrapping machine conveyor and upwardly inclined and declining conveyor troughs for each row of sandwiches, elevating one row of sandwiches and diverting this row over a next adjacent row and lowering this row on top of the next adjacent row of sandwiches and moving the sandwiches out of the paths of the accelerating conveyor flights as picked up by other conveyor flights, making it possible to have final production rates of 300 or more packages per minute with no damage to the cookies because of this high speed operation.
