Abstract
To palletize packages, a wrapping vehicle includes a vertically mounted drive screw having a plurality of ball nuts mounted at wrapping-effective distances from each other on the vertically mounted drive screw. Each ball-nut has a corresponding cantilever mounted to the ball nut to support a roll of wrapping material. A tension adjustment mechanism is mounted to adjust the resistance to motion of each roll of wrapping material and thus the tension on the wrapping material. The ball nuts are each connected to side support guide plates positioned to slide against the sides of mast housing the drive screw wherein said ball nuts are supported against tilting movement.

A method of wrapping a group of objects comprising the steps of:
- selecting a number of rolls and widths of wrapping material for wrapping the group of objects;
- mounting each of the selected number of rolls of wrapping material on a corresponding one of vertically-movable ball-nut driven cantilevers, whereby each roll of wrapping material may have its width and tension individually adjusted;
- moving the selected number of rolls of wrapping material as a group to a selected vertical height;
- fastening one end of each of the selected number of rolls of wrapping material onto at least one object of the group of objects;
- and
- moving the selected number of rolls of wrapping material and the group of objects with respect to each other, whereby the group of objects are wrapped simultaneously with the wrapping material from the selected number of rolls of wrapping material.
