An automatic fabric pattern-matching apparatus for, a fabric (MA) which has a pattern continuous at least in the lateral direction and which is unwound and spread from a wound fabric (M) and is fed from one end thereof in the longitudinal direction of the fabric in a hanging manner via a feeding mechanism of the fabric pattern-matching apparatus. The surface of the hanging portion of the fabric (MA) fed in the hanging manner is read by a CCD camera functioning as an optical reading apparatus, so that the vertical position of the fabric (MA) is controlled for aligning the fabric pattern so as to form a lateral straight line, based on the read signal. As a result, disadvantageous phenomena such as bias or bowed patterns created by gravity are eliminated, thereby eliminating defective products due to the disadvantageous phenomena noted. Also, a pattern matching operation of a fabric, which is conventionally considered difficult, can be surely, precisely, and efficiently realized by the automatic fabric pattern-matching apparatus.
