<p>Apparatus (20) for forming a panel (P) to a predetermined cross dimension by flangers (22,24,26,28) which form flanges (90,132) on the opposite side edges of the panel (P). The flangers (22,24,26,28) are movable toward and away from advanced positions in which to form the flanges (90,132). The advanced positions can be adjusted depending on the cross dimension desired. The flangers (22,24,26,28) can be retracted to permit loading and unloading of panels (P). Forming units (30,32) are also provided to form tabs (194) on an end of the panel (P).</p> |
