Kinky Chains

To repair a kinked herringbone chain, start by using pliers to gently push the bent links down.  Then use a regular wallpaper roller to flatten the links.  Be sure to roll on a sturdy surface.  Once the chain is flat again, polish it at the bench with a small, rotating brush.  Do not use a large polishing machine, as chains can get caught in the buffs.
