Abstract
An accumulator system for foldable sheet-like material. The system includes an accumulator bin having a pair of sidewalls, a pair of end walls, a bottom wall, and an open top. An infeed mechanism conveys the material to the accumulator bin. A chute receives the material from the infeed mechanism and guides the material inside the chute. In a first state, the chute is stationary and the system operates in a steady-state condition with a loop in the material between the infeed mechanism and an outfeed mechanism. In a second state, the outfeed mechanism is shut off and the chute is capable of reciprocating such that the material is guided toward the bottom wall of the bin. The reciprocating motion of the chute causes the material to be folded endwise in alternating fashion.
