而且，如圖4所示，若使雷射振盪器74作動並對左右一 對鏈齒排30之下止擋部50之形成位置照射雷射光74L，則 左右一對鏈齒排30之下端部之嚙合狀態之複數個鏈齒31之 嚙合頭部31a之表面將會熔融，使得經熔融之嚙合頭部 彼此以連結之方式固著，從而形成下止擔部$ 〇 C 再者，作為拉鏈製造裝置70之變形例，如圖5所示，亦 可更具備壓緊構件75，該壓緊構件75係可上下移動地設置 於基台71與雷射振盪器74之間，自上方按壓經熔融之複數 個嚙合頭部3 1 a。 壓緊構件75包含可透射雷射光74L之材料而成，作為具 體之材料’可使用硒化鋅（ZnSe)或者鍺（Ge)。又，於壓緊 構件75之下表面，以可有效地僅按壓經熔融之複數個嚙合 頭部31a之方式，沿著鏈布2〇之長度方向形成有刳面大致 為梯形之凸部75a。又，凸部75a之前端面（下表面）以不妨 礙雷射光74L通過之方式形成為平面狀。 如以上說明所述，根據本實施形態之拉鏈之止擋部形成 方法，由於藉由利用雷射光74L使左右一對鏈齒排3〇之下 端部之嗜合狀態之複數個鏈齒31之嚙合頭部3 la彼此溶融 固著而形成下止擋部50，因此，可自製造裝置7〇中去除驅 151787.doc 201208602 動裝置或包含南價材料之零件，使製造裝置7〇變得價廉， 從而可降低拉鏈10之製造成本。又，與使用金屬製或樹脂 製之下止具之情形相比，可使拉鏈1〇輕量化以及平坦化， 並且可易於回收化。又，由於雷射光74L進行非接觸加 工，因此，不會產生加工零件之損耗等，可永久性地進行 穩定之加工。又，由於無需驅動裝置或超音波產生裝置， 因此’可降低製造裝置之噪音。 又’作為本實施形態之拉鏈10之變形例，如圖6以及圖7 所示，亦可藉由雷射光74L來形成上止擋部8〇。如圖8所 示，該上止擋部80，係利用雷射光74L，使鏈齒排3〇之上 端部之鏈齒30之連結部3 Id與下壓腳部3丨0之交界部分產生 溶融’並藉由上述塵緊構件75來按壓經熔融之交界部分， 使之固著於鏈布20之上表面而形成。再者，圖中之符號 係鏈齒3〇與鏈布2〇之焊接部。 【圖式簡單說明】 圖1係對經實施本發明之拉鏈之止擋部形成方法所得之 拉鏈進行說明之表面圖。 圖2係圖1之A-A線剖面圖。 圖3係對實施本發明之拉鏈之止擋部形成方法之拉鍵势 造裝置進行說明之側視圖。 、 圖4係圖3之線剖面圖。 圖5係與說明拉鏈製造裝置之變形例之圖4對應之部分 剖面圖。 圖6係對經實施本發明之拉鏈之止擋部形成方法所得之 151787.doc 201208602 拉鏈之變形例進行說明之表面圖。 圖7係圖6之C - C線剖面圖。 圖8係表示形成圖7所示之上止擋部之狀態之剖面圖。 【主要元件符號說明】 10 拉鏈 20 鏈布 20a 鏈布側緣部 21 鏈條 30 鍵齒排 31 鏈齒 31a 嚙合頭部 31b 上壓腳部 31c 下壓腳部 31d 連結部 32 芯線 33 縫線 40 滑件 41 拉片 50 下止擋部 60 一對上止擋部 70 拉鏈製造裝置 71 基台 72 導親 73 一對進料輥 151787.doc 201208602 74 雷射振盪器 74L 雷射光 75 壓緊構件 75a 凸部 80 上止擋部 81 焊接部 151787.docFurther, as shown in FIG. 4, when the laser oscillator 74 is actuated and the laser light 74L is irradiated to the position where the stopper portion 50 is formed under the pair of left and right element rows 30, the lower end portions of the pair of left and right element rows 30 are provided. The surface of the engaging head portion 31a of the plurality of sprocket teeth 31 in the engaged state is melted so that the melted meshing heads are fixed to each other to form a lower stop portion $ 〇 C, which is manufactured as a zipper. As shown in FIG. 5, a modification of the device 70 may further include a pressing member 75 that is vertically movable between the base 71 and the laser oscillator 74, and is pressed and melted from above. The plurality of meshing heads 3 1 a. The pressing member 75 is made of a material that can transmit the laser light 74L, and as a specific material, zinc selenide (ZnSe) or germanium (Ge) can be used. Further, on the lower surface of the pressing member 75, a convex portion 75a having a substantially trapezoidal surface is formed along the longitudinal direction of the chain fabric 2 so as to effectively press only the plurality of molten engaging head portions 31a. Further, the front end surface (lower surface) of the convex portion 75a is formed in a planar shape so as not to block the passage of the laser light 74L. As described above, according to the method of forming the stopper of the slide fastener according to the present embodiment, the meshing of the plurality of fastener elements 31 of the in-line state of the lower end portions of the pair of left and right fastener elements is caused by the laser light 74L. The heads 3 la are melted and fixed to each other to form the lower stopper 50. Therefore, it is possible to remove the 151787.doc 201208602 moving device or the component containing the southern material from the manufacturing device 7〇, so that the manufacturing device 7 is inexpensive. Thereby, the manufacturing cost of the zipper 10 can be reduced. Further, the zipper 1 can be made lighter and flatter than the case of using a metal or resin lower stopper, and can be easily recycled. Further, since the laser light 74L is subjected to non-contact processing, it is possible to permanently perform stable processing without causing loss of the machined parts or the like. Further, since the driving device or the ultrasonic generating device is not required, the noise of the manufacturing device can be reduced. Further, as a modification of the slide fastener 10 of the present embodiment, as shown in Figs. 6 and 7, the upper stopper portion 8A can be formed by the laser light 74L. As shown in FIG. 8, the upper stopper portion 80 is made to melt the boundary portion between the joint portion 3 Id of the fastener element 30 and the lower presser portion 3丨0 at the upper end portion of the element row 3 by the laser light 74L. It is formed by pressing the melted boundary portion by the above-described dust-tight member 75 and fixing it to the upper surface of the chain fabric 20. Further, the symbol in the figure is a welded portion of the fastener element 3〇 and the chain cloth 2〇.
