Abstract:
To provide a device for tensioning a web such as a plastic web dispensed from a shuttle in a wrapping machine.
The wrapping machine includes an endless track positioned about an object to be wrapped and the shuttle travels on the endless track, dispensing the web as it goes. The rate at which web is dispensed varies as the shuttle progresses around the track and is dependent upon the shape of the track and the shape of the object to be wrapped.

The rollers are urged together to form a nip with the elastic material of the rollers compressed in the nip. The web is fed between the nips of the rollers.
