A stretch head for facilitating the wrapping of palletized loads within packaging or wrapping film comprises a vertical downright, a carriage assembly movable along the vertical downright, a base plate mounted upon the carriage assembly and inclined with respect to a horizontal plane so as to have a first end thereof disposed at a higher eleva- tion than a second opposite end thereof, a supply roll of wrapping or packaging film rotatably mounted upon the first higher end of the base plate, a pair of tension rollers mounted upon the base plate, a strain gauge roller mounted upon the base plate for receiving the wrapping film exiting from the tension rollers, a first idler roller mounted upon the base plate for receiving the wrapping film from the strain gauge roller, and a second idler roller for receiving the wrapping film from the first idler roller and mounted upon the lowest end portion of the base plate so as to be capable of positioning the wrapping film at the lowest ele- vation whereby the wrapping film can be wrapped around the lowermost regions of the palletized load. The second idler roller also comprises a rubberized sleeve member for pre- venting movement of the wrapping film in an axial direction along the external periphery of the second idler roller so as to ensure proper positioning and orientation of the wrap- ping film with respect to the palletized load.
