Herein, what is a hem bend?
The term hemming has its origins in fabric making where the edge of cloth is folded back on itself and then stitched shut. In sheet metal hemming means to fold the metal back on itself. Create a bend with Acute Angle Tooling in the metal, 30° is preferable but 45° will work for some circumstances.
Similarly, how is hemming done? The most common hem folds up a cut edge, folds it up again, and then sew it down. The style of hemming thus completely encloses the cut edge in cloth, so that it cannot unravel. Other hem styles use fewer folds.
