A succession of like textile fabric pieces is placed in a series on a conveyor which runs through an automated sewing station. There is some space between individual pieces. Immediately prior to the sewing station, the lateral disposition of a critical site on the piece about to be sewn and then being sewn is automatically sensed and, if necessary, automatically shifted to a uniform disposition. Preferably any error in original placement of the pieces is in placing the edge too far over in one lateral direction, so that if any adjustment is necessary, it takes the form of pushing the respective fabric piece edge margin laterally of the conveyor toward the opposite edge of that fabric piece. Thus, it is generally not necessary to laterally drag the whole fabric piece laterally of the conveyor, but only necessary to move a small marginal portion of the fabric piece. The necessary movement preferably is effected by a narrow, needle-like air jet which points generally upwardly, but can be automatically arcuately moved about a horizontal axis which extends longitudinally of the conveyor run. A control system incorporating a microprocessor is described. A typical use of the invention is for the sewing rib-knit cuff strip onto fleece-knit sweatshirt sleeve ends and rib-knit waistbanding on the lower edge of fleece-knit jacket bodies.
