ABSTRACT:
The invention consists of a process to form low stretch-deep draws on metal sheet; it foresees an initial stage through which a sequence of thread-like cuts (2) are carried out on the metal sheet (1) corresponding to the surface that will be drawn, whose cuts (2) on the adjacent lines are offset compared with each other, a stage in which the metal sheet (1) is stretched, through which stage the opening of the cuts (2) is obtained, therefore an ample widening of the cut surface and a minimum stretching of the non cut surface and of the oblique stripped metal network, separating the empty spaces (3) obtained through the widening of the thread like cuts (2), and where necessary, a stage in which the metal sheet is bent along a line which allows, on the overlapped surfaces, the open spaces of one surface to correspond to the strips on the other surface in order to reduce or close the width of the spaces in order to reduce electromagnetic interferences.
