Roll form tooling tryout and troubleshooting

Two design considerations facilitate easier tooling setup: using feeler hubs and aligning material faces. Feeler hubs are the gaps between the outer flanges of mating rolls. If the roll tooling is designed for 0.068-inch material, the designer should gap the feeler hubs at 0.068 in. This allows the setup person to use the material to set the gap.
