大きな問題となっている。However, in the tape-shaped female snap fastener manufactured by the above method, FIGS.
As shown in FIG. 7, a plurality of holes (holes reaching the tape 2) 10a, formed by the protrusions 15a, 15b, are formed in resin portions of the female member 3 located on both sides of the tape 2, respectively.
10b is formed, and the tape 2 can be seen at the bottom of the holes 10a and 10b. Since the tape-shaped female snap fastener is used by sewing the tape part to clothing,
The back surface side portion 3B of the female member 3 is concealed by the tape and the clothes in the use state. Even if a hole is formed in this portion, there is no problem in terms of design at all.
Since the front side portion 3A is not concealed even in the use state where the tape portion is sewn on clothes, it is very obstructive if there are many holes 10a in the front side portion 3A. In addition, since these holes 10a reach the tape 2 and the tape 2 is visible at the bottom of the hole 10a, when the color of the tape 2 and the color of the female member 3 are different, the tape 2 exposed at the bottom of the hole 10a The appearance is bad and the design,
It is a big problem.

That is, according to the first aspect of the present invention, a first mold in which a molding chamber having a shape corresponding to the front side of the female member is formed, and a molding chamber having a shape corresponding to the rear side of the female member are formed. By injecting a synthetic resin from a gate formed in the first mold into a molding chamber of the first mold while holding a tape in which a through-hole is formed in advance with the second mold, The synthetic resin is injected into the molding chamber of the second mold through the through-hole, and the female member integrated with the tape is molded. A plurality of protrusions are provided in a molding chamber of a mold, and a first mold is provided near a through hole of a tape which is movable up and down in the molding chamber when the tape is sandwiched between a first mold and a second mold. By pressing against the protrusion by the pressure of the synthetic resin injected into the molding chamber of the mold By the pressure of synthetic resin and said projections are characterized in that so as to position around the through hole of the tape at a predetermined position within the thickness of the female member.

ことになる。According to the above arrangement, when the tape is held between the first mold and the second mold, the vicinity of the through hole of the tape is
It is not held by the protrusion provided in the molding chamber of the second mold,
Although it is in a state in which it can freely move up and down in the molding chamber (a state in which it can move freely), when a synthetic resin is injected from the gate formed in the first mold into the molding chamber of the first mold, the tape causes pressure The through hole is pressed against a protrusion in the molding chamber of the second mold, and is positioned at a predetermined position within the thickness of the female member by the pressure at the time of injection of the synthetic resin and the protrusion.

なる。In particular, when the top surface of the projection is inclined so as to become lower toward the center of the molding chamber of the second mold, the protrusion is formed in the first mold. The synthetic resin injected into the molding chamber of the first mold from the gate is guided to the center side of the molding chamber of the second mold by the inclined top surface of the protruding part. It can be pressed against the protruding part by being dragged toward the center of the molding chamber of the second mold, and the pressure at the time of injection of the synthetic resin and the positioning of the vicinity of the through hole of the tape by the protruding part can be performed more reliably. Will be.
