Abstract
A stretch wrapping apparatus includes a dispenser for dispensing stretch wrap packaging material. The dispenser includes upstream and downstream prestretch rollers for engaging and stretching stretch wrap packaging material. The dispenser also includes an intermediate orienting roller positioned between the upstream and downstream prestretch rollers. The intermediate orienting roller abuts one of the upstream and downstream prestretch rollers, and is spaced from the other of the upstream and downstream prestretch rollers. Relative rotation is provided between the dispenser and the load to wrap the stretch wrap packaging material around the load.

A stretch wrapping apparatus comprising:
- a dispenser for dispensing stretch wrap packaging material including
- upstream and downstream prestretch rollers for engaging and stretching stretch wrap packaging material, and
- an intermediate orienting roller positioned between the upstream and downstream prestretch rollers, abutting one of the upstream and downstream prestretch rollers and spaced from the other of the upstream and downstream prestretch rollers, for changing the direction of curvature and forming an S-shaped pattern of stretch wrap packaging material where the intermediate orienting roller abuts the abutting one of the upstream and downstream prestretch rollers;
- and
- means for providing relative rotation between the dispenser and a load to wrap the stretch wrap packaging material around the load.
