<p>In accordance with the present invention, an improved apparatus (10) and method for prehemming and hemming is provided. More particularly, the improved apparatus (10) and method is for folding an edge portion of a curved arcuate panel to create a hem in a singl cycle of operation with a single hemming swing steel (28) pressed only in the vertical direction. The apparatus and method use an anvil (20) for supporting an associated assembly of the outer skin (12) and the inner panel (14), an upper body (27), and a steel (28) mounte to the upper body. The steel (28) is moved between first and second operative positions and has a first angled surface (52) for prehemming the assembly when the steel is in the first operative position and a second angled surface (50) for full-hemming the assembly when the steel is in the second operative position.</p> |
