A locker patch attachment system (30) for attaching a locker patch (10) having an arcuate edge (12) to a garment (11) by sewing about the arcuate edge of the locker patch as the garment and locker patch are automatically pivoted about a sewing machine (32) by a patch pivot assembly (70) and a body pivot assembly (105). The patch pivot assembly (70) and body pivot assembly (105) rotate at the same angular speed and about the common axis α which is displaced from the needle (22) of the sewing machine (32). The patch pivot assembly (70) includes a pivot plate (72) that holds the garment and locker patch in a fixed, overlaid relationship and rotates in order to pivot the garment and locker patch about the sewing machine (32). The body pivot assembly (105) includes a body gripping arm (108) and body panel plate (152) that engage and hold the body portion (16) as the body pivot assembly (105) rotates about the sewing machine (32), maintaining the locker patch and garment in a fixed radial alignment as they are pivoted about the sewing machine (32). A stacker (211) automatically removes the garment from the sewing machine (32) once the locker patch has been attached thereto.
