ABSTRACT:
An apparatus for stacking a plurality of folded box blanks such that alternating groups of a predetermined number of folded blanks are superimposed in opposite orientations. The apparatus includes a lower rail device having a stacking position, a second rail device above the first rail device and terminating at a position above an intermediate portion of the lower rail device, an inverting and transferring device for inverting alternating stacks of a predetermined number of folded blanks stacks at the stacking position onto the second rail device, a stopper device for allowing alternating stacks to move along the lower rail device, and a conveying device for conveying both the stacks on the lower rail device and the upper rail device simultaneously so that each stack on the upper rail device falls onto a stack on the lower rail device at the end of the upper rail device, whereby the desired combined stack is formed on the lower rail device.
