Abstract
An apparatus for drawing a metal sheet. In one implementation the apparatus includes a fixed head having a first window through which the metal sheet to be drawn may pass and a first holder for holding a first portion of the metal sheet within the first window during a drawing process. The apparatus also includes a moving head that is moveable relative to the fixed head. The moving head has a second window through which the metal sheet to be drawn may pass and a second holder for holding a second portion of the metal sheet within the second window during a drawing process. A support assembly is attached at one end to the fixed head and extends longitudinally through the second window of the moving head. The support assembly forms a part of an actuator assembly that is operable to situate the moving head in different and fixed longitudinal positions relative to the fixed head prior to a drawing process.
