Abstract
Corner controller (62) (FIG. 5) includes a conically shaped corner control wheel (90) that is rotated so as to apply a sweeping motion against the facing surface of the textile segment (12). This results in removing any folds or wrinkles from the textile segment as it moves to the sewing station (64). The corner control wheel is up the sewing path, ahead of the turning axis (111) of the textile segment. Therefore, when the textile segment is turned by the turning plate (45) through 90.degree. to form a curved corner about the textile segment (FIG. 6), the corner control wheel (90) urges the corner to move through its turning motion, so as to avoid nonuniform turning of the corner and any wrinkling of the corner material, and therefore avoiding the doubling up or bunching of the stitches formed about the rounded corner of the final textile segment.
