Patent ID: RE42417

Claim:
A rollforming station for a rollforming apparatus for forming profile shapes in a formable material, the rollforming station comprising: a tooling pedestal including means for mounting the tooling pedestal on the rollforming apparatus, a rollforming head mounted on said tooling pedestal, said rollforming head having a first tooling roller rotatably mounted on a first shaft supported by said pedestal, a second tooling roller rotatably mounted on a second shaft, said first and second tooling roller cooperating to form profile shapes by transversely deflecting said formable material into a shape having a nonplanar cross-section, and means rotatable mounted on said pedestal for supporting the second shaft eccentrically with reference to the centre of the second tooling roller so that a force applied in the direction of material feed through the tooling rollers will increase a tooling gap between the first and second tooling rollers, and an automatic gauge adjustor including means for resisting the movement of the second tooling roller to increase the tooling gap, said resisting means applying a force sufficient to achieve the rollforming action while allowing movement of the second tooling roller about the eccentric supporting means so that the second tooling roller will move against the resisting means in the direction of the material feed to accommodate the gauge of material being formed.
