Short answer: Hemming folds the edge of a sheet back onto itself to stiffen the panel, hide the sharp raw edge and improve safety and appearance — flat hems for simple stiffening, tight (closed) hems for safe, fully enclosed edges, and rolled hems that capture a wire or form a smooth round trim. It is a standard operation in ductwork, automotive body panels, appliance wrappers and enclosure seams, performed on a brake, roll-former or dedicated hemming die.
