An automatic drapery straightener is provided to promptly correct distortion of drapery by installing additional straightening unit and detecting unit, thereby minimizing loss of cloth and improving straightening performance. Skew rollers(30) and bow rollers(40) straighten cloth while rotating. A plurality of guide rollers(50) guides the cloth. A detecting unit(60) detects the straightened cloth. A control unit(120) controls the skew rollers and the bow rollers according to a detection signal. A second straightening unit(140) is formed under the detecting unit, and has second skew rollers(150) for secondarily straightening the primarily straightened cloth. A second detecting unit(160) is formed under the second skew rollers, and has a light emitting part(161) and a light receiving part(162) for detecting the secondarily straightened cloth and outputting a detection signal to the control unit.
