ABSTRACT:
Apparatus for conforming laminate to a radius edge. The apparatus includes a heat bar assembly including a heat plate extending longitudinally along the radius edge. A mechanism is attached to the assembly for applying uniform pressure to the laminate longitudinally along the radius edge for uniform heating of the laminate. The mechanism may include a plurality of selectively controllable cylinders spaced longitudinally within the heat bar assembly for pre-stressing at least a portion of the heat plate relative to the heat bar assembly. Additionally, the heat bar assembly may further include a cooling plate, where the heat bar assembly is rotatable along its longitudinal axis between a cooling and a heating position.
