Abstract
A belt loop is made by folding the longitudinal edges of an elongated fabric strip over a strip of fusible material and then heating the folded strip until the fusible material diffuses into the fabric and not only bonds the folded edges to the strip but also fuses together the fabric fibers to prevent fraying.
