Abstract
Process for cold forming metal sheet between a male and a complementary matrix of a die, in which the sheet is taken by each of a pair of opposite margins to allow that sheet to be subjected to tension in one dimension while the other pair of opposite margins are left free, characterized in that one or each of said subject margins is controlled positionally during the closing movement of the die, constricting it by means of respective articulations that move along an arched path extending longitudinally to the travel of the relative closing of the die and presents its concave side in the direction of said path, so that there is a relative component of movement of the said margins subject to, separating from each other and that the sheet in the aforementioned dimension within the some limits above its elastic limit, before the sheet is embedded between the male and die die.
