Abstract
A load portion is engaged in an infeed area and transported from the infeed area to a wrapping area with rotational, horizontal, and vertical carriers. Those carriers move the portion of the load horizontally along two horizontal degrees of freedom and one vertical degree of freedom by rotating a portion of the load about a vertical axis and translating the portion of the load along a generally linear horizontal direction and a generally linear vertical direction. The load is disengaged in the wrapping area and a stretch wrap packaging material dispenser is engaged and is transported to the wrapping area by the same rotational, horizontal, and vertical carriers to wrap the portion of the load with stretch wrap packaging material by using, once again, the same rotational, horizontal, and vertical carriers to rotate the dispenser around the load.
