A pre-hemming apparatus for use with a hemming die includes a driving member adapted to be centrally disposed below the hemming die. A plurality of link arms are operatively, pivotally connected to the driving member. A lever arm is operatively connected to each link arm. A flanging member is operatively connected to each lever arm at an end thereof. A plurality of mounts for supporting the lever arms are adapted to be mounted to a side of the hemming die. Each lever arm is pivotally connected to one of the mounts intermediate ends of the lever arm. An actuator is operatively engagable with the driving member. Actuation of the driving member moves the flanging members towards the hemming die through the lever arms and the link arms for pre-hemming, and away from the hemming die cycling the apparatus.
