ABSTRACT:
In forming a metal plate or the like into a helical seam pipe, the plate is deformed by bending rolls each made up of individual forming rolls. The forming rolls are exposed to shearing forces if the plate varies its direction of travel toward the forming rolls. To prevent the continued presence of shearing forces, the forming rolls are pivotally mounted on a support which is displaceably guided within a holder and an adjusting mechanism is connected to the support and the forming rolls to adjust the setting angle of the forming rolls in accordance with the direction of travel of the plate toward the forming rolls.
