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.
Claims6
A non-frayable fabric loop comprised of an elongated fabric strip of a first material whose longitudinal edges are folded over itself and a second material, whose melting point is lower than the scorching point of the first material, and which is entirely diffused between the fibers of the fabric strip, including the folded over edges, to hold them in their folded position and to fuse together the fibers of the fabric strip to prevent fraying.
A non-frayable fabric loop comprised of an elongated fabric strip of a first material whose longitudinal edges are folded over itself and a second material, whose melting point is lower than the scorching point of the first material, and which is diffused throughout the fibers of the fabric strip to fuse them together whereby fraying is prevented and the longitudinal edges of the first strip are maintained in their folded condition.
