Abstract
The waist band (16) is placed in straddling relationship about spindles (12-15). The waist edge (23) of the shirt body (17) is telescoped about the waist band, also in straddling relationship about the spindles (12-15). The garment parts are advanced by the rotation of the spindles and the sewing needle (9) forms a line of stitching at the aligned edges of the shirt body and waist band. In the meantime, the end spindles (14 and 15) move laterally of the sewing path to adjust the position of the waist band in response to the position of the folded edge (21) of the waist band as detected by photocell (30/138), and the star wheels (32) (FIGS. 5-7) reach across the waist band and urge the shirt body toward or away from the sewing path as controlled by the photocell (31/208). When the previously sewn edges of the garment parts begin to return to the sewing machine, one of the spindles (15) moves laterally so as to stretch the garment parts mores so as to remove any bunching of the waist edge of the shirt body at the sewing needle and presser foot, to avoid forming a wrinkle in the shirt body at the end of the line of the stitching.
