ABSTRACT OF THE DISCLOSURE In a method and apparatus for applying a protective strip by sewing to an end of a slide fastener, a continuous protective strip is fed downwardly toward a tape supply position on the base of a sewing machine with its one surface facing opposite to a direction of feed of a slide fastener until a leading end portion of the protective tape overlays the base by a predetermined length, then the leading end portion is bent in a direction opposite to the fastener feed direction by a stream of pressurized air issued from an air nozzle, thereafter, a slide fastener is advanced along the base until its leading end reaches to a sewing position located downstream of the tape supply position, thereby causing the leading end portion of the protective tape to bend into a U-shape extending from the back to the face of the slide fastener around the leading end thereof, then the U-shaped leading end portion is cut from the continuous protective tape, thereby forming a U-shaped protective strip which in turn is sewn to the leading end of the slide fastener.
