ABSTRACT:
The invention is a method and apparatus for separating by a pivoting motion a stack formed of a plurality of layers of die cut corrugated board and thereafter delivering separated portions of the stack while minimizing damage to the respective portions. The apparatus comprises a conveyor for delivering stacked portions to be separated, a means for securing portions of the stacked board to portions of the conveyor, and a means for pivoting a portion of the conveyor and a secured stacked portion of the board thereon to thereby pivotally separate the stacked portions from one another along a connecting thin paper web. The method comprises advancing a first and second stacked portion to be separated to a position beneath a securing means, securing the first and second stacked portions by a first and second press device, pivoting the second conveyor portion and secured second stacked portion thereon about an axis parallel to the line of thin paper web connecting the stacked portions, lowering the second conveyor portion and secured second stacked portion, and then delivering a separated stacked portion to a separate roller conveyor. The method for separating requires less force than conventional separators and thereby advantageously reduces damage caused to the top layer of the stacked portions of board.
