ABSTRACT:
In a preferred embodiment, an automatic sheet-stacking and stack transporting machine, transporting and depositing single sheet-line forms onto free-wheeling machine rollers above an elevator, a limit switch rearwardly located to activate an aligning lever and to retract the free-wheeling machine rollers to thereby drop rollers-supported sheets onto the platform rollers and to further initiate lowering of the elevator platform rollers sufficiently downwardly to break the electrical circuit to terminate the downward movement until a subsequent activation of the limit switch by deposit of another sheet, a maximum stacking load switch mechanism being activatable when the elevator platform rollers have been lowered to a maximum predetermined limit whereupon the elevator lowers to a take-off position at which take-off position interspersed take-off driven rollers transport the aligned stack of sheets from the machine to a distant unloading point, and thereafter the elevator rises upwardly to the original depositing position.
