Abstract: The mill stand comprises forming rolls, which have congruent forming elements, mounted on a stand frame member in such a way that one of the forming rolls is adapted for a vertical reverse motion. This forming roll is connected with a hydraulic cylinder provided with control means, interacting with a master device operatively connected with one of the forming rolls.

Abstract: A mill comprises at least one rolling stand with rolls having congruent lengthwise arranged forming elements, a drive stand and apparatus for locally heating a sheet metal at its portions to be transversely deformed or corrugated. The apparatus for locally heating the sheet metal includes inductors and a cam mechanism adapted to move said inductors up to and down from the sheet metal. The distributing shaft of the cam mechanism is connected through a transfer mechanism with one of the rolls of the rolling stand. The gear ratio of the transfer mechanism is equal to the number of the forming elements of one of the rolls of the rolling stand. The mill is simple in construction and easy to re-adjust when producing sheet panels with another spacing between the deformed portions or corrugations.
