(About flat curved slide fasteners)
The flat curved slide fastener S1 according to the embodiment of the present invention is composed of two fastener tapes 1 and 1 shown in FIG. 1 and a metal slider 3 shown in FIG. 2, and the fastener tape 1 is made of metal service teeth. A dentition mounting portion 10 for mounting the dentition row 20 in which 21 is arranged in the longitudinal direction, an attachment base 11 formed on the outer side of the dentition attachment portion 10, and further provided adjacent to the outside from the attachment base 11. The mounting edge portion 12 is formed.

  Here, the dentition row 20 attached to the dentition attachment part 10 forms a ridge that is continuous in the longitudinal direction together with the dentition attachment part 10. Further, the attachment base portion 11 of each fastener is located outside the service gear attachment portion 10 as described above, and is formed by the weft 120 and the warp 110. The width of the attachment base portion 11 is very small, and in this embodiment, the width is about 1 millimeter and is continuous in the longitudinal direction along the tooth attachment portion 10. By reducing the width of the attachment base 11 in this way, the flexibility of the planar curved slide fastener is enhanced by forming an attachment edge made of only weft as much as possible while maintaining the reinforcing effect. Is configured to be possible.

  The weft 120 in the attachment base 11 extends in the outer edge direction as it is, and the attachment edge 12 having a width of about 8 mm in this embodiment is formed only by the weft 120. The weft 120 in this embodiment uses twisted yarn, and when the twisted yarn is unwound, the weft 120 has a configuration in which a very large number of ultrafine fibers 120a are formed in the shape of a brush hair.

  The flat curved slide fastener S1 according to the present embodiment is obtained by cutting the outer edge with a blade such as a heel slightly in the tape base 14 in the slide fastener using the fabric composed of the warp yarn 110 and the weft yarn 120 made of thermoplastic synthetic fiber. The part from the outside removes the warp 110 to such an extent that it does not affect the arrangement of the dentitions, forms the attachment edge 12 that becomes only the weft 120, and forms the detachment base 11 near the dentition 20 In this case, the warp yarn 110 is left as it is, so that a large number of the ultrafine fibers 120a are formed in the shape of a brush. The number of the warp yarns 110 is not particularly limited, but in this embodiment, about four warp yarns are left. In addition, the present invention is not limited to this embodiment, and a very good flat curved slide fastener can be obtained by leaving approximately 5 to 6 warps.

  In the present invention, the warp yarn 110 is not manufactured only by the method, but the warp yarn 110 is not provided in advance to the attachment edge portion 12 instead of removing the warp yarn 110 from the ready-made slide fastener shown in this embodiment. It can also be formed as a planar curved slide fastener S having only 120.

Therefore, in the present invention, the width of the mounting base 11 corresponding to the durability and the curvature to be used can be set as appropriate, not limited to the one disclosed in the above embodiment. Further, even if the attachment base portion 11 is not provided, the attachment base portion 11 can be omitted if the engagement tooth attachment portion 10 and the engagement tooth row 20 do not lose shape or drop off the engagement teeth.

  On the other hand, in the above embodiment, the width of the slider 3 in the planar curved slide fastener S1 is substantially the same as the width of the service tooth 21 to be combined, but the width of the slider 3 is smaller than the width of the service tooth 21. You can also On the contrary, although it is possible to make the width of the slider 3 larger than the width dimension W1 of the engagement tooth 21, if the width is made smaller than the lateral width dimension W2 of the curved long hole 40 formed in the cloth 4 to be attached. Good. It should be noted that by allowing the slider 3 to have a certain width, it is possible to obtain an advantageous effect in terms of the design of the slider 3 and ease of picking.

A large number of ultrafine fibers 120a, which are the wefts 120 of the mounting edge 12 to be arranged, are arranged so that the vicinity of the ends overlap each other, and all of them enter the ultrafine fibers 120a and are melted and solidified. It is fixed by. Therefore, there is no gap at all between the attachment target fabric 40 and the planar curved slide fastener S1.

(Second flat curved slide fastener mounting structure)

As for the configuration of the planar curved slide fastener S1, the planar curved slide fastener S1 according to the above-described embodiment is similarly used in this mounting structure. In the following configuration, the same portions are denoted by the same reference numerals for description.

  As shown in FIG. 6, the mounting structure of the planar curved slide fastener S <b> 1 according to the embodiment is the planar curved shape along the edge in the curved long hole 40 formed in the fabric that is the fabric to be mounted 4. The dentition 20 of the slide fastener S1 is provided, and is thermally bonded between the lower surface in the vicinity of the curved elongated hole 40 and the upper surface of the mounting edge portion 12 of the planar curved slide fastener S1 in the fabric 4 to be mounted. The member 5 does not intervene, and the thermal bonding member 5 covers the attachment edge 12 on the lower surface side of the flat curved slide fastener S1 and the attachment object cloth 4 on the peripheral edge thereof, and the overlapping part (attachment object cloth and The heat bonding member 5 penetrates to the attachment target fabric 4 side and melts and solidifies at a large number of welding points 44 where the attachment target fabric 4 and the attachment edge portion 12 communicate with each other. Configuration .

  In this configuration, a large number of holes 42 associated with the formation of the welding points 44 are formed in the dough 4 to be attached in the overlapping portion. In addition, as described above, the thermal bonding member 5 is configured to cover the attachment target fabric 4 from the attachment edge portion 12 of the left and right tape bases 14 constituting the flat curved slide fastener S1 from the lower surface side to the peripheral portion. By doing so, there is no gap at all between the attachment object fabric 4 and the planar curved slide fastener S1.

(Attaching method of first flat curved slide fastener)
Next, the mounting structures 1 and 2 of the planar curved slide fastener S1 according to the embodiment of the present invention using the planar curved slide fastener S1 according to the present invention are implemented. The mounting method is shown below.

(Attaching method of the first planar curved slide fastener S1)
A mounting method (hereinafter referred to as a first mounting method) of the first planar curved slide fastener S1 for realizing the first mounting structure described above is performed according to the following procedure.
First, the thermal bonding fabric 5 is polymerized on the mounting target fabric 4, and the mounting target fabric 4 and the thermal bonding fabric 5 are continuously melted from the thermal bonding fabric 5 side by a CO ₂ gas laser to form a curved long hole 40. . At this time, the heat bonding fabric 5 is melted and temporarily fixed to the attachment target fabric 4 only at the edge of the curved elongated hole 40 by heat generated by fusing.

  Next, the process which attaches the planar curved slide fastener shown in the said Example with respect to the said curved long hole 40 using an ultrasonic welding machine is performed. The attachment target fabric 4 and the thermal bonding fabric 5 are superposed with the thermal bonding fabric 5 side down, and further, the flat curved slide fastener S1 below and the slider S mounting side as the top surface. Since the width of the curved elongated hole 40 is formed larger than the width of the slider S and the width of the dentition 20, the slider S and the dentition 20 are accommodated in the curved elongated hole 40.

  Here, the ultrasonic welding machine has a pressure sandwiching structure with a pressure roller 60 on the upper side and a horn 61 that vibrates up and down with ultrasonic waves on the lower side, while performing ultrasonic welding, It has a function of sending out by rotating in the circumferential direction with reference to the central axis and rotating in the circumferential direction with reference to the longitudinal central axis of the horn 61.

  In this embodiment, as shown in FIGS. 7 and 8, the planar curved slide fastener S1 is disposed on the lower side, and the attachment target fabric 4 is disposed on the upper side with the thermal bonding fabric 5 facing downward, and is superposed. An ultrasonic welding process is performed by inserting between the pressure roller 60 and the horn 61.

  Here, the pressure roller 60 includes a small-diameter portion 64 at a longitudinal center position, pressurizing portions 62 and 62 that are adjacent to the left and right of the small-diameter portion 64 and have a larger diameter than the small-diameter portion, and further pressurizing portions 62 and 62. Rotating shafts 65 and 65 provided adjacent to the left and right outsides are integrally provided. Here, the height dimension H2 of the step formed by the small-diameter portion 64 and the pressing portion 62 is set to be larger than the height H1 of the dentition portion of the planar curved slide fastener and the height of the slider. Further, a convex portion 63 for forming the welding point 43 is continuously formed on the pressurizing portions 62 and 62 over the entire circumference. In the present embodiment, the convex portion 63 is formed in a truncated cone shape. And the width dimension W3 of the gap | interval part between the pressurization parts 62 and 62 is taken as the dimension substantially the same as the width dimension W2 of a curvilinear long hole.

  By using the pressure roller 60 having the above-described configuration, the attachment target fabric 4 moves in the left-right direction of the horn 61 (the central axis of the pressure roller 60) due to the displacement of the relative position with the curved elongated hole 40 formed in the attachment target fabric 4. Even if there is a deviation in the longitudinal direction), the dentition 20 of the planar curved slide fastener S1 is guided from between the pressure portions 62, 62 of the pressure roller 60- without being detached, and the planar curved slide fastener The mounting edge 12 capable of exhibiting the flexibility of the above is provided with a configuration consisting of only the weft 120, so that it is fitted between the pressure roller 60 and the horn 61, and the dentition 20 is formed from the curved elongated hole 40. Since it does not come off, the pressure roller 60 and the roller 60 are not particularly conscious of the fact that the curved elongated hole is formed in a curved shape without being influenced by the displacement of the attachment target fabric 4. Simply sequentially sent throughout the chromatography emissions 61, it is possible to attach well very appearance of the flat curved slide fastener against curved slot.

  By the ultrasonic welding, the attachment edge portion 12 of the flat curved slide fastener S1 and the attachment target fabric 4 can be attached integrally by the melted and solidified thermal bonding member 5.

(Attaching method of second flat curved slide fastener)
Next, the procedure of the mounting method of the second planar curved slide fastener S1 (hereinafter referred to as the second mounting method) for realizing the above-described second mounting structure will be described below.
First, as for the method of attaching the planar curved slide fastener, the curved elongated hole 40 is formed by fusing only the material to be attached with a CO ₂ gas laser using a laser processing machine.

  Next, the planar curved slide fastener S <b> 1 and the thermal bonding member 5 are sequentially arranged below the attachment target fabric 4. Here, the planar curved slide fastener S1 has a configuration in which the dental dentition 20 is fitted into the curved elongated hole 40, and the attachment edge portion 12 is in contact with the lower surface of the attachment target fabric 4, and further, a thermal bonding member 5 is configured to cover from the attachment edge 12 of the left and right tape bases 14 to the attachment target fabric 4 at the peripheral portion thereof. In this state, the ultrasonic welding process is performed by passing between the pressure roller 60 and the horn 61 of the ultrasonic welding machine.

  Also in the present embodiment, the ultrasonic welding machine used in the first attachment method is used, and the pressure roller 60 is adjacent to the small diameter portion 64 at the longitudinal center position and the left and right of the small diameter portion 64 and the small diameter portion. The pressure parts 62, 62 having a diameter larger than 64 and the rotating shaft part 65 provided adjacent to the left and right outer sides of the pressure parts 62, 62 are integrally provided. The small diameter part 64 and the pressure part The height dimension H1 of the step formed by 62 is made larger than the height of the engagement tooth 21 of the planar curved slide fastener S1 and the height of the slider 3, and a welding point 44 is formed on the pressing parts 62, 62. The convex part 63 for forming is continuously formed over the entire circumference, and the width dimension W3 of the gap part between the pressure parts 62 and 62 and the width dimension W2 of the curved elongated hole 40 are substantially the same dimension. It is said.

  Therefore, also in this embodiment, as in the case of the first attachment method, the attachment target fabric 4 is moved in the left-right direction (additional) of the horn 61 by the displacement of the relative position with respect to the curved elongated hole 40 formed in the attachment target fabric 4. Even if there is a deviation in the longitudinal direction of the central axis of the pressure roller 60, the dentition row 21 of the planar curved slide fastener S1 is guided from between the pressure parts 62, 62 of the pressure roller 60, Since the mounting edge portion 12 on which the flat curved slide fastener S1 can exhibit flexibility is provided with a configuration composed of only the weft 120, the slide tooth fastener 21 is fitted between the pressure roller 60 and the horn 61, and the dentition 21 is curved. Since it does not come off from the elongated hole 40, it is not affected by the displacement of the dough 4 to be attached, and is simply sent out sequentially between the pressure roller 60 and the horn 61 so as to have a planar curved shape. It has the advantage of being able to attach very appearance good ride fastener S1 against curved slot 40.

  In the second attachment method of the flat curved slide fastener S1, the thermal bonding member 5 is melted and solidified with respect to the attachment target fabric 4 and the tape base 14 by ultrasonic welding, and the attachment edge 12 in the tape base 14 is obtained. Is coated with the thermal bonding member 5, and the convex portion 63 forming the welding point 44 welds the attachment object fabric 4 and the tape base 14 of the flat curved slide fastener S 1, and the thermal bonding member 5 is melted. It solidifies after entering the tape base 14 and the attachment target fabric 4.

  Further, the tape base 14 is made of a thermoplastic synthetic fiber, so that the tape base 14 itself is in a slightly melted state due to heat, and becomes more familiar with the heat bonding member, thereby strengthening the mutual bond. Then, the coating of the heat bonding member 5 on the tape base 14 also exhibits the effect of suppressing the wear of the tape base 14 due to rubbing or the like, and the durability as a whole can be greatly improved.

  As shown in the first mounting structure, the second mounting structure, the first mounting method, and the second mounting method, in this embodiment, the fabric 4 to be mounted is a fabric, but the pressure applied by the pressure roller 60 By forming the partial welding points 43 and 44 by the convex part 63 provided in the parts 62 and 62 and leaving the non-welding points 45, the burden of heat acting on the attachment target fabric 4 can be greatly reduced. And knitted fabrics and stretch fabrics can also be used.

  Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment. For example, as a means for forming the curved elongated hole 40 in the attachment target fabric 4, In addition to the melting by the disclosed laser, fusing using an ultrasonic welding machine can be performed, and instead of the curved long hole 40, one end of the curved long hole is attached as shown in FIG. A curved notch 46 having a shape opened at the end of the fabric 4 may be used.

  Further, the curved shape of the curved elongated hole 40 or the curved notched portion 46 is not limited to the embodiment, and can be various curved shapes according to design requirements such as various wave shapes and semicircular arc shapes. Some may include straight lines.

  Further, the thermal bonding member 5 uses a thin hot melt adhesive film in this embodiment and is very suitable in that it has excellent flexibility. However, the present invention is not limited to this. In addition, general hot melt adhesive films such as polyamide and polyester can be used, and as a thermal adhesive member, not only film-like ones but also web-like, powdery ones, etc. can be used. it can.

  Furthermore, as another example of the mounting structure of the planar curved slide fastener S1, the mounting structure in which the configurations of the first mounting structure and the second mounting structure are combined, that is, like the first mounting structure, A thermal bonding member 5 is interposed between the flat curved slide fastener S1 and another thermal bonding member 5 for coating the mounting edge 12 from below the flat curved slide fastener as in the second mounting structure. It can also be set as the structure provided. In this case, as shown in the first attachment method, when the curved elongated hole 40 is formed, the attachment target fabric 4 and the heat bonding member 5 are superposed to form the curved elongated hole 40, and the planar curved slide fastener S1 is formed. Can be obtained by superimposing another thermal bonding member 5 covering the flat curved slide fastener S1 and performing ultrasonic welding.

  Further, in the above-described embodiments, in the first mounting structure and the first mounting method, it is not always necessary to form the welding point 43 and the non-welding point 45, and the flexibility of the overlapping portion is somewhat impaired, but the curved length The whole can be welded along the hole 40.

  The present invention relates to the flat curved slide fastener S and its mounting structure, etc. Of course, the flat curved slide fastener S according to the present invention is used by being attached to the attachment object fabric 4 as a straight line. You can also.

  In the present invention, the slider 3 and the tooth set 20 need not be made of metal, and heat-resistant synthetic resin or the like can be used.

  Furthermore, as another embodiment of the planar curved slide fastener according to the present invention, as shown in FIG. 9, the mounting edge 12 of the planar curved slide fastener S (S2) is made of a thermoplastic synthetic resin having elasticity. It can also be formed as a network structure. In this case, when a conventional knitted fabric or stretchable fabric is used, the knitted fabric or stretchable fabric is easily melted when the slide fastener is welded to the fabric to be attached, and a product of sufficient quality is manufactured. However, it is possible to attach a flat curved slide fastener to the knitted fabric or stretchable fabric, which is very preferable because it can produce a variety of products in a new field that has never existed before. Even when the flat curved slide fastener S2 is used and the mounting structure is the same as that of the flat curved slide fastener S1, the mounting edge portion made of a knitted structure or a network structure using a stretchable material provides sufficient heat. Since the bonding area with the adhesive material can be ensured, it can be reliably fixed to the attachment target fabric in any direction and curvature.
