Abstract
An improved bundle former for corrugated paperboard boxes in which the timing of the lift mechanisms and the squaring plates is completely independent of the timing of the flexo-folder-gluer. Also, the stacking belt drive roll is mounted near the pull roll so its top periphery is below the path of box travel. This permits the folded box to contact the stacking belt tangentially, thereby easing the box's entry into the stacking station and providing an assist in squaring the box in the stack. The improved bundle former also includes simpler and more easily maintained elements.
