Abstract
A hemming apparatus comprises a main die configured to supports panels to be hemmed together. The main die is raised and lowered between a home position and a hemming position by a drive using a fixed cam and a moveable cam. The apparatus also includes a hemming die assembly having a pre-hemming and final hemming die block mounted on a frame. An electromechanical motor assembly drives the frame along an inclined path. Shot pins are provided to lock the frame into positions for pre-hemming and final hemming. The frame travels along ways and surfaces associated with frame travel are hand scraped to provide a precision movement of the frame for accurate and consistent hemming operations.
