The invention relates to a device for unwinding strips (10) for a stamping machine (1) capable of accumulating the strip to be stamped (20 in a pre-unwound form between at least one stamping spool (3) and a platen press (310) of the stamping machine (1), characterized in that the device for unwinding strips (10) comprises: a central drum (11) configured to be rotated at a variable feed rate, rotatably secured to an axis of the strip unwinding device (10), - a satellite roller (14) having an axis arranged parallel to the axis of the central drum (11), the satellite roller (14) being capable of turning around the central drum (11), the pre-unwound strip being capable of winding around the central drum (11) under the effect of the movement of the satellite roller (14), and - a planetary drive device (15) for moving the satellite roller (14) around the central drum (11) according to the difference in speeds of rotation of the central drum (11) and of an external ring (13) of the planetary drive device (15) configured to be rotated at a constant speed in a direction of rotation that is counter to the direction of rotation of the central drum (11). The invention also relates to a stamping machine (1) configured to place on each sheet the gilded or metalized film from at least one strip to be stamped (2).
