Ah ok, I do not know the name for that particular tool but I've seen them in use for sheetmetal bending in large quantities.

The device the OP linked to is meant to be hand operated and only for small series. Setup takes forever and then some, redoing a setup for another batch is impossible because it will all come out slightly different.

That 'press brake' uses a tool-and-die style mechanism to deform the sheet, very accurate and highly repeatable, quick as well, cycle time is a few seconds.
