ABSTRACT:
An apparatus for forming a portion of a member to a predetermined reference position includes a sensor which locates the actual position of the member. A positioning device positions first and second panel holding members into position to engage the member at the actual located position of the member. A drive unit moves the first and second holding members into engagement with the member to hold the member in a fixed position. The drive unit also moves a forming member into engagement with the member to form a portion of the member between the holding members to the predetermined reference position. A pierce pin, also operated by the drive unit, optionally punches an aperture in the formed portion of the member. A method of forming a portion of a member to a known reference position employs the above-described elements. The method also includes the steps of initiating the movement of the holding members before initiating movement of the forming members such that the holding members engage the member prior to engagement of the forming member with the member.
