A forming method and an upper stopper forming apparatus thereof.

Generally, a zipper 100 is formed by forming teeth 112 of a metal or a synthetic resin material on opposite sides of a pair of tapes 110 so that teeth are engaged with each other as shown in FIG. 6. The two lines are pushed to the slider 120 and pulled to open and close. Pants, skirts, jumpers, etc. are widely used in clothes and pockets, purses, bags and shoes. At this time, the upper and lower ends of the tape 120, each of the film welding portion 114 is formed to facilitate the formation of the pin and pin box to be described later while increasing the hardness of the tape, the upper side of the teeth formed on the distal end of the slider The upper stopper 115 is formed to prevent the pin, and the pin 116 and the pin box 118 are formed by pressing or molding the film welding portion of the lower portion.

A conventional method of manufacturing the zipper 100 used as described above, first, the fabric, wherein the fabric is a plurality of teeth 112 on the opposite sides of the pair of tapes 110 as shown in Figure 7a. ) Is fixed along the length direction, and it is interlocked with its teeth, and it is made to be short from several meters to hundreds of meters.

The fabric thus supplied removes the teeth 112 fixed to the tape 120 at a predetermined position of the intended use or desired length by the length required by a conventional zipper gapping machine as shown in FIG. 7B. This removal process is performed, and the film is welded to the tape () of the portion where the tooth is removed by a conventional film welding machine as shown in FIG. 7C to form the film welding portion 114. A film welding process is performed. At this time, the film welding part serves to reinforce the fabric as well as to fix the pin and the pin box formed on the lower end of the zipper to be described later.

Then, a punching operation is performed on the film welding portion 114 to fix or form the pins and the pin box by a conventional punch machine as shown in FIG. 7D, and the film welding portion 114 of the punched portion is illustrated in FIG. Pins and pin boxes made of metal are pre-fabricated as shown in 7e, and then press-fixed to each other, or liquid pins and pins 116 and pins of synthetic resin are supplied through a conventional injection molding machine, that is, liquid and pins on pins and pin box molds. A pin and pin box molding process for molding the box 118 is performed.

Then, after inserting and engaging the slider 120 as shown in FIG. 7F on the teeth 112 of the tape 110 on the opposite side where the pin and the pin box are not formed, the slider is combined with the tip shown in FIG. As described above, the upper stopper 115 of the metal material is pressed or fixed so as not to be separated, or molded into a synthetic resin, and then cut between the pin box 118 and the upper stopper 115 as shown in FIG.
