ABSTRACT:
An apparatus for folding the minor flaps of an unfolded sleeve around an item to be packaged, thereby minimizing the amount of handling required. The apparatus folds a sleeve around the item to be packaged. The sleeve has four walls, each wall having a lower edge defining a lower perimeter, and further having a first and second unfolded panel extending downwardly from the walls. The apparatus comprises a first fold bar located upstream of the box, and a second fold bar located downstream of the box. Each fold bar has a folding portion located at substantially the same height as the perimeter, such that when the fold bar is moved into contact with an unfolded panel, the fold bar contacts and folds an unfolded flap into the plane of the perimeter. In a preferred embodiment, the first fold bar is moved into contact with a first panel, and the sleeve is moved downstream to cause the second fold bar to contact the second panel.
