Abstract
Abstract A stripping and stacking machine including a continuous suction conveyor comprising a rotary impactor capable of stripping and feeding previously die-cut cardboard blanks to a segmented, perforated suction conveyor. The suction conveyor operates continuously to carry the previously die-cut and stripped cardboard blanks to a predetermined location whereat a vertically reciprocal grid system activated by an automatic signal operates to separate the said blanks from the conveyor and deposits the blanks upon a descending pallet elevator system.
