Abstract: A system for coiling film onto a mandrel includes a film coiling device and a supply roll of film. The film coiling device includes a rotational drive device that is operable to rotate a mandrel to coil film from the supply roll onto the mandrel. The tension device is operable to provide a selected amount of tension on the film between the supply roll and the mandrel. A tension monitoring device is operable to determine a change in tension of the film between the supply roll and the mandrel. A control is operable to adjust a rotational speed of at least one roller to adjust the relative rotational speed of the supply roll and the rotational drive device to adjust the tension in the film. After the film is coiled around the mandrel, the film is cut and the mandrel and coiled film is removed from the film coiling device.
