Description of the Invention [Technical Field] The present invention relates to a method for manufacturing a fastening tape, and more particularly to a method for manufacturing a mushroom head fastener fastening tape with a mushroom head fastener Buckle belt. [Prior Art] Hook-and-loop fasteners are a variety of conventional fasteners and are widely used in various fields where there is a need for adhesives, such as clothing, backpacks, and wire finishing. and many more. The hook and loop fastener is mainly composed of a fastening tape on which a plurality of fasteners are formed and a fabric tape on which a plurality of fabric loops are formed and penetrates/separates through the fastener and the fabric loop To achieve the effect of the buckle / detachment. As shown in FIG. 1, the manufacturing method of the fastening tape substantially comprises: adding the thermoplastic plastic raw material 1 to the plastic extruder 2; and injecting the molten plastic from the extrusion machine into a plurality of mold rolls 3 In the cavity 4 on the outer circumferential surface; after the mold roll is cooled, the release tape 7 on which the plurality of small studs 6 are formed is pulled away from the mold roll by using the release roll 5; and the forming roll 8 is used to make the small protrusion The free end of the column is shaped into a hook member 9 of the desired shape. Figure 2 and Figure 3 respectively show the structure of two conventional mushroom head clasps, wherein Figure 2 shows a round-headed mushroom head clasp formed by a cylindrical stud (Figure 2b) (Figure 2b); And Figure 3 shows a long elliptical head mushroom head clasp formed by a quadrangular stud (Fig. 3b) (Fig. 3b). Although these two head-shaped mushroom head clasps can achieve a certain function of the adhesive function, they also have their own shortcomings of -4- 201010633. For example, the round-shaped hook member shown in Fig. 2 is effective for the hook member and the fabric loop because the rounded periphery does not provide a slanting angle of the hook fabric loop when it is engaged with the fabric loop. The buckle ratio is low, and there is a disadvantage of insufficient adhesive force. In addition, such a round-shaped hook member can form an effective buckle only when the fabric loop is completely inserted into the round head. Although the buckle can provide a very reliable adhesive, when separated, It is true that the buckled fabric loop is broken and broken. Therefore, after several times of use, the ratio of the loop of the fabric loop 0 is increased, and the adhesive ability of the fastener strip and the fabric loop is drastically reduced, and even becomes There is no adhesive effect, so there is a shortcoming of short service life. The long elliptical head mushroom head hook member shown in Fig. 3 can provide an effective hook with the fabric loop at both ends of the elliptical-shaped long axis, and can provide a higher hook than the above-mentioned round-shaped hook member. The buckle ratio and the greater adhesive strength, but 'this type of hook member only forms an effective hook with the fabric loop at both ends of its elliptical long axis, so it can only be parallel to the oval In the long axis direction, β provides an effective bonding force, and the effective fastening provided in the direction perpendicular to the long axis of the ellipse is relatively limited. In other words, the hooking action of this type of hook member and the fabric loop is directional and does not provide a uniform, non-directional, uniform fastening effect. Therefore, when the hooking of the hook member of this type and the loop of the fabric are subjected to an external force in a specific direction (for example, a direction perpendicular to the long axis direction of the ellipse), the accidental loosening may occur due to the situation The problem of insufficient reliability of the hook-like hooks. In view of the above-mentioned problems of the conventional mushroom head clasps, the adhesive tape industry is capable of producing a uniform fastening effect with a high fastening ratio, a long service life, and providing a non-square-5-201010633 directionality. There is a demand for a high-quality mushroom head hook-and-hook fastener tape and a mushroom head hook-and-loop fastener tape. SUMMARY OF THE INVENTION One object of the present invention is to provide a mushroom head buckle hook fastener capable of producing a high-viscosity rate, a long service life, and a non-directional uniform bonding effect and high reliability. The method of belt, which can be achieved by a method for manufacturing a φ fastener tape, comprising: providing a rotatable mold cylinder having a plurality of γ-shaped cavities on the outer circumferential surface and a cooling inside Providing an extruder having an outlet nozzle, the set nozzle being disposed adjacent to an outer circumferential surface of the mold cylinder and having a gap between the set nozzle and an outer circumferential surface of the mold cylinder; Supplying a thermoplastic to the extruder, and allowing the thermoplastic to be melted in the extruder and ejected from the set nozzle onto the peripheral surface of the outer circumference of the mold cylinder and into the cavity; a plastic on the outer circumferential surface of the mold cylinder and in the cavity for forming a fastening strip having a plurality of hook members molded on one surface thereof, wherein each of the hooks has a shape a free end of the V-shaped; peeling the fastening tape from the mold cylinder; and feeding the fastening tape through a pair of rotating rollers, wherein the roller roller is in contact with the V-shaped free end of the original shape of the buckle It is heated above the temperature of the plastic deformation of the plastic to deform the V-shaped free end of each of the fasteners into a polygonal hook-shaped head portion, thereby forming a polygonal shape with a polygonal shape of -6-201010633 Mushroom head clasps. In accordance with an embodiment of the present invention, the hook member is formed such that the plane of the two-legged arms of the V-shaped free end including the V-shaped free end is parallel to the direction in which the fastening strip is fed through the roller. Another object of the invention is to provide a mushroom head clasp fastening strip made by the above method. Φ [Embodiment] The method of the present invention and the mushroom head clasp fastener tape manufactured by the present invention will now be described with reference to the embodiments shown in Figs. 4 and 5. " Fig. 4 is a schematic view showing a fastening-belt manufacturing apparatus 10 for carrying out the method of the present invention. The apparatus 10 primarily includes a rotatable mold cylinder 20, an extruder 30, a stripper roller 40 and a pair of wheel rollers 50 and 52. The mold cylinder 20 has a plurality of cavities 22 formed in a Y-shape formed on an outer circumferential surface thereof and a cooling device (not shown) is disposed inside the mold cylinder, such as a cooling water circulation system. The extruder 30 includes a frit chamber 32 surrounded by a heating coil 33, a feed tank 34 disposed at one end of the frit chamber, and an operatively coupled end to the other end of the frit chamber. An injection nozzle 36 is disposed, which is disposed adjacent to an outer circumferential surface of the mold cylinder 20 and forms a space with the outer circumferential surface. This spacing can be varied by adjusting the distance relative to the outer circumferential surface. In carrying out the method of the invention, a thermoplastically deformable plastic (such as 'polyethylene) is first fed from the feed tank 34 into the extruder 30, and the plastic is heated in the melt chamber 32 via a heating coil (eg, heated) To about 23 5, it is 201010633 to be melted, and then the molten plastic is ejected to the outer circumferential surface of the mold cylinder 20 via the injection nozzle 36 and injected into the cavity 22. After the outer circumferential surface of the mold cylinder 20 and the plastic in the cavity 22 are cooled and solidified by the cooling device of the mold drum 20, the yarn is detached from the mold cylinder 20 by the pulling of the mold release roller 40 to form a fastener. The belt 60 has a substrate 62 and a plurality of hook blanks 64 integrally molded on a surface of the substrate. The fastening strip 60 is then fed through a φ of a pair of wheel rollers 50' 52. As shown in FIG. 5, in this embodiment, each of the clasps 64 is formed as a polygonal column-shaped stud (for example, one of the figures shown as a rectangular post) and includes a stem. 66 and a free end 68 that is folded into a V shape. In addition, in the embodiment shown in Figure 5, the hook blank 64 is formed such that the plane of the two furcation arms including its V-shaped free end 68 is parallel to the direction in which the fastening strip is fed through the roller. D. The roller 50 of the pair of wheel press rolls 50, 52 which is in contact with the hook blank 64 is heated by φ and maintained at a temperature at which the plastic is plastically deformed (for example, 130 ° C in the case of polyethylene). In addition, a gap is formed between the roller cylinders 50, 52 for the passage of the fastening tape, the gap being adjustable such that the distance of the gap is smaller than the thickness of the substrate of the fastening tape plus the original shape of the buckle The sum of the heights. Thereby, when the fastening strip 62 passes between the rollers 25, 52, the V-shaped free end 68 of the hook blank 64 can be wheeled into a polygonal shape (as in the illustrated embodiment). In the octagonal shape) head 68', as shown in Fig. 5, the hook member manufactured according to the method of the present invention has a polygonal head -8-201010633 head' thus providing a plurality of fabric loops Effectively hooking the corners, thereby increasing the adhesion rate with the fabric loop and producing a dense adhesive effect. Further, since the hook member of the present invention is hooked to the fabric loop by the corner of the polygonal head, the fabric loop is not broken when disengaged, so that the service life of the fastener strip can be prolonged. In addition, the polygonal head of the clasp member of the present invention substantially provides a slanting angle capable of forming an effective hooking with the fabric loop at each of the positions, so that the fastening strip of the present invention is engaged with the φ of the fabric loop. It is a comprehensive and non-directional cooperation. Although the manufacturing method and the fastening tape of the present invention have been described above with reference to the preferred embodiments shown in the drawings, this does not mean that the invention is limited only to the structures described above and shown in the drawings. And operation. In fact, the present invention may be susceptible to various modifications and changes. For example, an auxiliary cooling device (for example, a cooling fan) may be disposed at a position of the mold drum 20 that is diametrically opposite to the injection nozzle 36 to provide additional φ cooling of the fastening strip on the mold cylinder. . All such modifications and variations are within the true scope of the invention as defined by the scope of the appended claims.
