ABSTRACT:
The present invention provides means for automatically adjusting rollforming equipment to accommodate a range of different gauges of material such as sheet metal being formed. One rollforming roller (34) on each rollforming head (4A) is mounted on an eccentric so that a force supplied in the direction of material feed through the tooling rollers (33,34) will increase the tooling gap therebetween. An automatic gauge adjustor includes applying a source of substantially constant pressure sufficient to achieve the rollforming action against rotation about the eccentric while allowing movement of the rollforming roller also about the eccentric so that the roll will move against the pressure being provided in the direction of the material feed to accommodate the gauge of material within the working range set. This allows the rollforming head (4A) to adjust the rolling gap between rollers to accommodate varying gauges automatically and with minimal or no lead in damage while the rolls adjust to the new gauge of material.
