Standard Accessories

Film Applicator

SWI provides a film applicator that is standard on all slitting/CTL lines. This film application method provides excellent runability and is also easy to adjust. A built-in braking system controls the tension at which the film is applied to the metal.

Feed Table

All SWI slitting/CTL lines come equipped with in-feed tables standard. This table serves two purposes. The first is, when coupled with an SWI uncoiler, the table allows one person to easily load the material into the machine. The second is to provide an area to easily apply the strippable film.
