Arc Rolls for Web Spreading
An arc roll carries a permanent bow that spreads the web sideways as it passes, removing wrinkles before they set into the reel. Bow height and wrap angle decide how much spreading you actually get.

Arc Roll — common questions
Where should an arc roll be installed?
Immediately before a nip or a winder — the point where a wrinkle would otherwise be pressed in permanently.
How is bow height selected?
By web width and how much spread is needed. Wider webs and stretchy grades need more bow, but too much bow causes edge flutter and baggy centres.
