ABSTRACT:
A reinforcement tape is stuck to an outer front surface of a fastener tape and a fastener element removed portion at a space portion, in which fastener elements are removed and to which the separable bottom end stop of the concealed type slide fastener, for example, a insert pin or the like is attached, by ultrasonic welding. The reinforcement tape may be, for example, a tape whose front surface is made of a thermoplastic elastomer film while its rear surface is made of hot melt adhesive agent. At the same time of the above sticking, an edge portion is formed into a U shape and its surface is reinforced and then, the insert pin or the like is attached to this portion. The fastener tape itself does not come into contact with a diamond of a slider, even if outer face of the U-shaped edge portion comes into sliding contact with the diamond, so the fastener tape is protected from being worn or damaged.
