Abstract

Plate which may have variable linear dimensions may be precisely deformed to form regular undulations. The process is carried out by means of a press with columns in two stages. In the first stage, carried out under moderate pressure, the jaws are brought into contact with the plate to measure the thickness at the level of each column. The second stage or undulation is carried out at high pressure and the upper mobile jaw is displaced a distance equal to the difference between the predetermined distance between the two planes at the level of the columns and the local thickness of the plate.
