Abstract
Abstract Methods and Apparatus for automatically advancing a length of ribbon from a roll, severing a desired length therefrom, turning the ends inwardly towards the center, folding the length generally centrally to position the cut ends generally adjacent within the central fold, positioning the double folded length to cover the end of a garment seam and stitching the resultant seam end cover to the garment.
