PURPOSE: A backlash control apparatus and method for a metal embosser machine are provided to improve the molding quality of a metal panel by minutely moving an adjustment gear from side to side in order to control backlash. CONSTITUTION: A backlash control apparatus for a metal embosser machine comprises a top forming roller, a bottom forming roller(10), a rotating gear, and an adjustment gear(26). The top and bottom forming rollers are respectively coupled to a column by a top shaft and a bottom shaft(14) and rotated with the power of a motor. The rotating gear is coupled to the top and bottom shafts and engaged with the adjustment gear. A sleeve(32) is fixed to the top and bottom shafts with a key(30) and formed with a collar(34). The adjustment gear is coupled to the sleeve and allowed to rotate from side to side and formed with a coupling groove(38) on the front where the collar is inserted. A fastening screw(28) is coupled to the adjustment gear by passing through the collar. A fastening hole(40) is formed to have a larger diameter than the fastening screw so that the adjustment gear can move minutely from side to side.
