Abstract
An automatic packaging machine includes a loading station for simultaneously and sequentially picking up a plurality of elongated products and deposing them in a spaced parallel alignment within a box. At the time of loading each of the products has an initial volume which is substantially greater than the volume which the same product will have after it has settled over time within the box. Thus, the box id overfilled by an amount which will make it full after the products have settled. Then, the overfilled box is advanced to a closing station, where the lid is closed over the filled box without damage to the products. This immediately reduces the volume of the products to the volume which they would have after they have settled.
