A device is provided for drawing sheet materials, in particular, sheet blanks. The device includes a cushion of elastic material disposed in an enclosure, a die for forming the sheet blank, the die having a peripheral portion constituting an upper blank holder. The device also includes a lower blank holder for supporting and maintaining at least a portion of the sheet blank which is placed directly on the cushion of elastic material and cooperates with the upper blank holder for clamping the sheet blank in at least localized zones. The lower blank holder bears against a slidable element disposed around lateral faces of the cushion.
