Machine for stretching metal sheets, which comprises a static support (3) and a moving support (4) that hold a metal sheet (2) during a process of stretching said metal sheet (2), and driving means (5) that cause a longitudinal movement of said moving support (4) in relation to said static support (3) during said process, a section (S) of said metal sheet (2) comprised between said supports (3,4) being stretched and tensioned. Said machine (1) also comprises a third support (6) that remains static during the stretching process and which is disposed between the static support (3) and the moving support (4), and the driving means (5) cooperate with said third support (6) in order to move said moving support (4) longitudinally during said stretching process.
