And a slider setting device 50 for correcting the inclination of the slider SL with respect to the transport direction. Note that the posture in which the length direction of the slide fastener SF in this embodiment is vertical is a posture in which the width direction of the pair of tapes T of the slide fastener SF is along the transport direction.
　ここで、スライドファスナーＳＦについて説明する。このスライドファスナーＳＦは、図１７に示すように、一対のテープＴと、一対のテープＴの対向するテープ側縁部にそれぞれ設けられる複数のエレメントＥと、一対のテープＴの複数のエレメントＥを噛合・分離させるスライダーＳＬと、一対のテープＴのエレメントＥの一端部にそれぞれ設けられる上止部Ｐａと、一対のテープＴのエレメントＥの他端部に設けられる下止部Ｐｂと、を備える。また、スライドファスナーＳＦは、テープ長さ調整装置１０に供給された時は、スライダーＳＬが上止部Ｐａから少し下止部Ｐｂ側に位置している。なお、エレメントＥは、金属製のエレメント、合成樹脂製のエレメント、コイル状のエレメントのいずれであってもよい。また、スライドファスナーＳＦは、スライダーの引手がある側が表側で、引手がない側が裏側である。また、スライダーＳＬは、図７中の左右方向に離間して配置される上板Ｄ１及び下板Ｄ２と、上板Ｄ１と下板Ｄ２とを連結する案内柱Ｄ３と、引手が取り付けられる引手取付柱Ｄ４と、を備える。 Here, the slide fastener SF will be described. As shown in FIG. 17, this slide fastener SF includes a pair of tapes T, a plurality of elements E respectively provided on opposite tape side edge portions of the pair of tapes T, and a plurality of elements E of the pair of tapes T. A slider SL for engaging and separating, an upper stop portion Pa provided at one end of the element E of the pair of tapes T, and a lower stop portion Pb provided at the other end of the element E of the pair of tapes T are provided. .. Further, in the slide fastener SF, when supplied to the tape length adjusting device 10, the slider SL is located slightly closer to the lower stop portion Pb side than the upper stop portion Pa. The element E may be a metal element, a synthetic resin element, or a coil-shaped element. Further, in the slide fastener SF, the side with the pull tab of the slider is the front side, and the side without the pull tab is the back side. Further, the slider SL includes an upper plate D1 and a lower plate D2 that are spaced apart from each other in the left-right direction in FIG. 7, a guide pillar D3 that connects the upper plate D1 and the lower plate D2, and a puller attachment to which a puller is attached. And a pillar D4.
　搬送装置２０は、図２及び図７に示すように、スライドファスナーＳＦの表面及び裏面を挟むように配置され、スライドファスナーＳＦを案内する一対のガイドレール２１と、一対のガイドレール２１上のスライドファスナーＳＦを上流側から下流側に搬送する搬送部材２２と、を備える。 As shown in FIGS. 2 and 7, the transport device 20 is arranged so as to sandwich the front surface and the back surface of the slide fastener SF, and has a pair of guide rails 21 for guiding the slide fastener SF and a slide on the pair of guide rails 21. A transport member 22 that transports the fastener SF from the upstream side to the downstream side.
　一対のガイドレール２１は、断面矩形状の棒状部材であり、前後方向に沿って平行に配置されている。そして、図７に示すように、一対のガイドレール２１間の間隔Ｔ１は、スライドファスナーＳＦのエレメントＥの厚みＴ２以上、スライドファスナーＳＦのスライダーＳＬの厚みＴ３以下に設定されている。これにより、スライドファスナーＳＦのスライダーＳＬが一対のガイドレール２１の上面に引っ掛かるため、スライドファスナーＳＦが下方に抜け落ちることはなく、前後方向に移動可能になる。スライダーＳＬの厚みＴ３は、スライダーＳＬの引手取付柱Ｄ４の上端（図７の左端）と下板Ｄ２の下面（図７の右側面）との間の距離である。また、一対のガイドレール２１間の間隔Ｔ１は、スライダーＳＬの上板Ｄ１の上面（図７の左側面）と下板Ｄ２の下面（図７の右側面）との間の距離Ｔ４以下に設定される方がより好ましい。これにより、スライダーＳＬの上板Ｄ１と下板Ｄ２の下端（図７の下端）の両方が一対のガイドレール２１の上面に支持されるため、スライダーＳＬの厚み方向の傾きを防止して、スライダーＳＬを安定した姿勢にすることができる。 The pair of guide rails 21 are rod-shaped members having a rectangular cross section and are arranged in parallel along the front-rear direction. Then, as shown in FIG. 7, the interval T1 between the pair of guide rails 21 is set to be not less than the thickness T2 of the element E of the slide fastener SF and not more than the thickness T3 of the slider SL of the slide fastener SF. As a result, the slider SL of the slide fastener SF is hooked on the upper surfaces of the pair of guide rails 21, so that the slide fastener SF does not fall downward and can be moved in the front-rear direction. The thickness T3 of the slider SL is the distance between the upper end (left end of FIG. 7) of the pull tab attachment pillar D4 of the slider SL and the lower surface (right side of FIG. 7) of the lower plate D2. Further, the interval T1 between the pair of guide rails 21 is set to a distance T4 or less between the upper surface (the left side surface in FIG. 7) of the upper plate D1 of the slider SL and the lower surface (the right side surface in FIG. 7) of the lower plate D2. Is more preferable. Accordingly, both the lower ends (lower ends in FIG. 7) of the upper plate D1 and the lower plate D2 of the slider SL are supported on the upper surfaces of the pair of guide rails 21, so that the slider SL is prevented from tilting in the thickness direction, and the slider SL is prevented. The SL can have a stable posture.
　搬送部材２２は、図１及び図７に示すように、ガイドレール２１と平行に配置される駆動ロッド２３と、駆動ロッド２３の上面に前後方向に等間隔に配置され、ガイドレール２１の上面側に延びる複数の搬送アーム２４と、を備える。 As shown in FIG. 1 and FIG. 7, the transport member 22 is provided with a drive rod 23 arranged in parallel with the guide rail 21 and an upper surface of the drive rod 23 at equal intervals in the front-rear direction. And a plurality of transfer arms 24 extending to the.
　駆動ロッド２３は、不図示の駆動装置により、上下方向に対して直交する水平面内において矩形状軌道（図１の矢印Ｍ参照）を描くように駆動される。搬送アーム２４は、断面矩形形状を有した板状部材、もしくは断面円柱形状または円筒形状を有した棒状部材であり、その先端は一対のガイドレール２１の左右方向中心よりも向こう側に達している。このため、図２及び図３に示すように、駆動ロッド２３が前側に移動する際に、搬送アーム２４がスライドファスナーＳＦのテープＴの側面に接触し、スライドファスナーＳＦを下流側に搬送する。これにより、搬送部材２２が矩形状軌道を描くように１回駆動する毎に、複数のスライドファスナーＳＦが等間隔で所定距離搬送される。つまり、複数のスライドファスナーＳＦは搬送部材２２により間欠搬送される。 The drive rod 23 is driven by a drive device (not shown) so as to draw a rectangular trajectory (see arrow M in FIG. 1) in a horizontal plane orthogonal to the vertical direction. The transfer arm 24 is a plate-shaped member having a rectangular cross section, or a rod-shaped member having a cylindrical shape or a cylindrical cross section, and its tip reaches beyond the center of the pair of guide rails 21 in the left-right direction. .. Therefore, as shown in FIGS. 2 and 3, when the drive rod 23 moves to the front side, the transport arm 24 contacts the side surface of the tape T of the slide fastener SF and transports the slide fastener SF to the downstream side. As a result, each time the transport member 22 is driven so as to draw a rectangular orbit, the plurality of slide fasteners SF are transported at equal intervals for a predetermined distance. That is, the plurality of slide fasteners SF are intermittently transported by the transport member 22.
　そして、搬送部材２２により搬送された複数のスライドファスナーＳＦの各停止位置は、各種の加工位置になり得る。本実施形態では、図２に示すように、１つの停止位置が待機位置ＷＰとなり、待機位置ＷＰに隣接する下流側の停止位置が加工位置ＣＰとなっている。待機位置ＷＰでは、下側グリッパ３２により、上止部ＰａがスライダーＳＬに接触するまでスライドファスナーＳＦのテープＴが引き下げられる（図４、図８参照）。切断位置ＣＰでは、レーザー加工部４０により、テープＴにおける上側グリッパ３１と上止部Ｐａとの間、及びテープＴにおける下側グリッパ３２と下止部Ｐｂとの間の２カ所が切断される（図５、図１１参照）。 Each stop position of the plurality of slide fasteners SF transported by the transport member 22 can be various processing positions. In the present embodiment, as shown in FIG. 2, one stop position is the standby position WP, and the downstream stop position adjacent to the standby position WP is the processing position CP. At the standby position WP, the lower gripper 32 pulls down the tape T of the slide fastener SF until the upper stop portion Pa contacts the slider SL (see FIGS. 4 and 8). At the cutting position CP, the laser processing section 40 cuts two places between the upper gripper 31 and the upper stop Pa of the tape T and between the lower gripper 32 and the lower stop Pb of the tape T ( (See FIGS. 5 and 11).
　上側グリッパ３１は、図２、図７、及び図９に示すように、一対のテープＴの上端部を挟持する左右のグリッパ部材３１ａを備える。左右のグリッパ部材３１ａは、ガイドレール２１の上方において、ガイドレール２１と平行に配置されている。左右のグリッパ部材３１ａは、不図示の駆動装置により、左右方向に開閉するように駆動される（図１０参照）。そして、上側グリッパ３１は、一対のテープＴの上端部を挟持することにより、一対のテープＴの上止部Ｐａよりも上側の部分の姿勢を左右方向において一定にすることができる。これにより、レーザー加工部４０によるテープＴの切断位置及び切断角度を一定にすることができる。 As shown in FIGS. 2, 7, and 9, the upper gripper 31 includes left and right gripper members 31 a that hold the upper ends of the pair of tapes T. The left and right gripper members 31 a are arranged above the guide rail 21 and in parallel with the guide rail 21. The left and right gripper members 31a are driven to be opened and closed in the left and right directions by a driving device (not shown) (see FIG. 10). The upper gripper 31 can hold the upper ends of the pair of tapes T, and thereby make the posture of a portion above the upper stop portions Pa of the pair of tapes T constant in the left-right direction. Thereby, the cutting position and the cutting angle of the tape T by the laser processing section 40 can be made constant.
　下側グリッパ３２は、図２、図７、及び図９に示すように、ガイドレール２１の下方において、ガイドレール２１と平行に配置される左右の駆動プレート３３と、左右の駆動プレート３３にそれぞれ取り付けられ、待機位置ＷＰにあるスライドファスナーＳＦの一対のテープＴの下端部を挟持する左右の第１グリッパ部材３４と、左右の駆動プレート３３にそれぞれ取り付けられ、加工位置ＣＰにあるスライドファスナーＳＦの一対のテープＴの下端部を挟持する左右の第２グリッパ部材３５と、を備える。なお、左側の駆動プレート３３は図示されていない。 As shown in FIGS. 2, 7, and 9, the lower gripper 32 includes a left and right drive plate 33 and a left and right drive plate 33, which are arranged in parallel with the guide rail 21 below the guide rail 21, respectively. The left and right first gripper members 34 that hold the lower ends of the pair of tapes T of the slide fastener SF that are attached and are in the standby position WP and the left and right drive plates 33 are attached to the slide fastener SF that is in the processing position CP. The left and right second gripper members 35 that sandwich the lower end portions of the pair of tapes T are provided. The left drive plate 33 is not shown.
　左右の駆動プレート３３は、不図示の駆動装置により、左右方向及び上下方向に駆動される。具体的には、左右の駆動プレート３３が左右方向内側に駆動することにより、第１及び第２グリッパ部材３４，３５が閉じてテープＴを挟持し、左右の駆動プレート３３が左右方向外側に駆動することにより、第１及び第２グリッパ部材３４，３５が開いてテープＴを解放する。そして、第１及び第２グリッパ部材３４，３５がテープＴを挟持した状態で、左右の駆動プレート３３が下方に駆動することにより、待機位置ＷＰ及び加工位置ＣＰにあるスライドファスナーＳＦのテープＴが同時に引き下げられる（図８、図１０参照）。 The left and right drive plates 33 are driven in the left and right direction and the up and down direction by a drive device (not shown). Specifically, when the left and right drive plates 33 are driven inward in the left-right direction, the first and second gripper members 34, 35 are closed to sandwich the tape T, and the left and right drive plates 33 are driven outward in the left-right direction. By doing so, the first and second gripper members 34 and 35 are opened to release the tape T. Then, with the first and second gripper members 34, 35 holding the tape T, the left and right drive plates 33 are driven downward, so that the tape T of the slide fastener SF at the standby position WP and the processing position CP is moved. At the same time, it is pulled down (see FIGS. 8 and 10).
　そして、第１グリッパ部材３４（下側グリッパ３２）がテープＴを引き下げることにより、待機位置ＷＰでは、上止部ＰａがスライダーＳＬに接触するまでテープＴが引き下げられる（図８参照）。また、第２グリッパ部材３５（下側グリッパ３２）がテープＴを引き下げることにより、加工位置ＣＰでは、テープＴに一定のテンションが付与される（図１０参照）。さらに、テープＴに一定のテンションが付与されることにより、一対のテープＴのスライダーＳＬよりも下側の部分の姿勢を左右方向において一定にすることができる。これにより、レーザー加工部４０によるテープＴの切断位置及び切断角度を一定にすることができる。なお、下側グリッパ３２の第１及び第２グリッパ部材３４，３５の挟持力は、テープＴを引き下げる力よりも低く設定されている。このため、上止部ＰａがスライダーＳＬに接触した後は、第１及び第２グリッパ部材３４，３５は、テープＴに対して滑るように下動するため、テープＴに過度な力が加わることがない。よって、テープＴの延びによる、テープＴの長さのバラつきが抑制される。 Then, the first gripper member 34 (lower gripper 32) pulls down the tape T, so that at the standby position WP, the tape T is pulled down until the upper stop portion Pa contacts the slider SL (see FIG. 8). Further, the second gripper member 35 (lower gripper 32) pulls down the tape T, so that a constant tension is applied to the tape T at the processing position CP (see FIG. 10). Furthermore, by applying a constant tension to the tape T, the posture of the portion of the pair of tapes T below the slider SL can be made constant in the left-right direction. Thereby, the cutting position and the cutting angle of the tape T by the laser processing section 40 can be made constant. The holding force of the first and second gripper members 34, 35 of the lower gripper 32 is set lower than the force of pulling down the tape T. For this reason, after the upper stop portion Pa contacts the slider SL, the first and second gripper members 34 and 35 slide downward with respect to the tape T, so that an excessive force is applied to the tape T. There is no. Therefore, variation in the length of the tape T due to the extension of the tape T is suppressed.
　レーザー加工部４０は、図９に示すように、加工位置ＣＰにおいて一対のガイドレール２１の左側に配置されており、テープＴにおける上側グリッパ３１と上止部Ｐａとの間を切断する上側レーザー照射部４１と、テープＴにおける下側グリッパ３２と下止部Ｐｂとの間を切断する下側レーザー照射部４２と、を備える。なお、本実施形態では、図１１に示すように、上側レーザー照射部４１は、テープＴの上止部Ｐａの直上を切断する位置に配置され、下側レーザー照射部４２は、テープＴの下止部Ｐｂの直下を切断する位置に配置される。また、図５及び図１１の符号Ｌは、上側及び下側レーザー照射部４１，４２のレーザービームである。 As shown in FIG. 9, the laser processing portion 40 is arranged on the left side of the pair of guide rails 21 at the processing position CP, and the upper laser irradiation for cutting between the upper gripper 31 and the upper stop portion Pa of the tape T is performed. A portion 41 and a lower laser irradiation portion 42 that cuts between the lower gripper 32 and the lower stopper portion Pb of the tape T are provided. In the present embodiment, as shown in FIG. 11, the upper laser irradiating section 41 is arranged at a position to cut immediately above the upper stop Pa of the tape T, and the lower laser irradiating section 42 is located below the tape T. It is arranged at a position for cutting just below the stop Pb. Further, reference numeral L in FIGS. 5 and 11 denotes laser beams of the upper and lower laser irradiation units 41 and 42.
　スライダーセッティング装置５０は、図９及び図１０に示すように、ガイドレール２１の上方に配置され、スライダーＳＬの表面及び裏面を挟む左右一対のクランパ５１を備える。左右のクランパ５１は、前後方向に沿って設けられる駆動軸５２に一端が取り付けられており、駆動軸５２の往復回転により開閉するように構成されている。また、左右のクランパ５１の他端部の対向面には、スライダーＳＬの一部の形状を象った凹部５１ａがそれぞれ形成されている。 As shown in FIGS. 9 and 10, the slider setting device 50 is provided above the guide rail 21 and includes a pair of left and right clampers 51 that sandwich the front surface and the back surface of the slider SL. One end of each of the left and right clampers 51 is attached to a drive shaft 52 provided along the front-rear direction, and the left and right clampers 51 are configured to open and close by reciprocal rotation of the drive shaft 52. In addition, recesses 51a each having a shape of a part of the slider SL are formed on the facing surfaces of the other ends of the left and right clampers 51, respectively.
　このように構成されたスライダーセッティング装置５０では、図１０に示すように、左右のクランパ５１を閉じて、左右のクランパ５１の凹部５１ａ内にスライダーＳＬの一部を入り込ませる。この際、スライダーＳＬは、上下方向においてスライダーセッティング装置５０とガイドレール２１との間に挟まれた状態となる。これにより、スライダーＳＬの搬送方向に対する傾きを修正することができるため、スライダーＳＬ、上止部Ｐａ、及びテープＴが所定の位置に位置決めされる。従って、レーザー加工部４０によるテープＴの切断位置及び切断角度を一定にすることができる。 In the slider setting device 50 thus configured, as shown in FIG. 10, the left and right clampers 51 are closed and part of the slider SL is inserted into the recesses 51a of the left and right clampers 51. At this time, the slider SL is in a state of being sandwiched between the slider setting device 50 and the guide rail 21 in the vertical direction. As a result, the inclination of the slider SL with respect to the transport direction can be corrected, so that the slider SL, the upper stop portion Pa, and the tape T are positioned at predetermined positions. Therefore, the cutting position and the cutting angle of the tape T by the laser processing section 40 can be made constant.
　仕分け部１２は、図１、図１２、及び図１３に示すように、搬送装置２０のガイドレール２１の下流側端部においてスライドファスナーＳＦを受け取り、下流側（図１２の左側）に搬送する搬送機６０と、搬送機６０を第１～第３排出位置Ｐ１～Ｐ３で停止させる第１～第３センサー７１～７３と、搬送機６０が搬送したスライドファスナーＳＦを収納ボックス９０に排出する排出装置８０と、を備える。 As shown in FIGS. 1, 12, and 13, the sorting unit 12 receives the slide fastener SF at the downstream end of the guide rail 21 of the transport device 20, and transports the slide fastener SF to the downstream side (left side in FIG. 12).

　左右の保持ロッド６２は、図１に示すように、スライドファスナーＳＦを受け取る位置において、一対のガイドレール２１に対して直線上に連続するように配置される。このため、搬送部材２２がスライドファスナーＳＦを左右の保持ロッド６２上に搬送することが可能になり、搬送されたスライドファスナーＳＦは左右の保持ロッド６２に保持される。また、左側の保持ロッド６２は、伸縮可能に構成されており、後述するガイド板８１上で左側の保持ロッド６２を縮めることにより保持したスライドファスナーＳＦを解放する。 As shown in FIG. 1, the left and right holding rods 62 are arranged so as to be linearly continuous with the pair of guide rails 21 at the position where the slide fastener SF is received. Therefore, the transport member 22 can transport the slide fastener SF onto the left and right holding rods 62, and the transported slide fastener SF is held by the left and right holding rods 62. The left holding rod 62 is configured to be expandable and contractible, and the slide fastener SF held by the left holding rod 62 is released by contracting the left holding rod 62 on a guide plate 81 described later.
　第１センサー７１は、第１排出位置Ｐ１に移動した搬送機６０を検出し、第１排出位置Ｐ１に搬送機６０を停止させる。第２センサー７２は、第２排出位置Ｐ２に移動した搬送機６０を検出し、第２排出位置Ｐ２に搬送機６０を停止させる。第３センサー７３は、第３排出位置Ｐ３に移動した搬送機６０を検出し、第３排出位置Ｐ３に搬送機６０を停止させる。このため、第１～第３排出位置Ｐ１～Ｐ３のいずれかに搬送機６０を停止させ、スライドファスナーＳＦを排出することが可能になる（図１４参照）。従って、例えば、第１～第３排出位置Ｐ１～Ｐ３のそれぞれにスライドファスナーＳＦを１０本ずつ排出することが可能である。また、センサー７１～７３は左右方向に移動可能であり、スライドファスナーＳＦの長さに対応して配置することができる。なお、センサーの数は、３つに限定されず、１つ以上であればよい。 The first sensor 71 detects the carrier 60 that has moved to the first discharge position P1 and stops the carrier 60 at the first discharge position P1. The second sensor 72 detects the carrier 60 that has moved to the second discharge position P2 and stops the carrier 60 at the second discharge position P2. The third sensor 73 detects the carrier 60 that has moved to the third discharge position P3, and stops the carrier 60 at the third discharge position P3. Therefore, it is possible to stop the transporter 60 at any of the first to third discharge positions P1 to P3 and discharge the slide fastener SF (see FIG. 14). Therefore, for example, 10 slide fasteners SF can be discharged to each of the first to third discharge positions P1 to P3. Further, the sensors 71 to 73 can be moved in the left-right direction and can be arranged according to the length of the slide fastener SF. Note that the number of sensors is not limited to three and may be one or more.
　排出装置８０は、図１２及び図１３に示すように、左右方向沿って配置され、搬送機６０により搬送されるスライドファスナーＳＦを案内するガイド板８１と、ガイド板８１の右側に隣接して配置され、スライドファスナーＳＦをガイド板８１の上面に案内する湾曲ガイド板８２と、ガイド板８１の下方に配置され、スライドファスナーＳＦを滑り落とすシュート板８３と、シュート板８３の下方に配置され、シュート板８３を滑り落ちたスライドファスナーＳＦを受け取るレシーブ板８４と、を備える。 As shown in FIGS. 12 and 13, the discharging device 80 is arranged along the left-right direction, and is arranged adjacent to the guide plate 81 that guides the slide fastener SF conveyed by the conveyor 60 and the right side of the guide plate 81.

The horizontal position of the guide plate 81 is a position for guiding the slide fastener SF (see FIG. 13), and the falling position of the guide plate 81 is to tilt the guide plate 81 downward to move the slide fastener SF to the chute plate 83. Position (see FIG. 15).
　レシーブ板８４は、左右方向に沿って設けられる駆動軸８４ａに一方縁が取り付けられており、駆動軸８４ａの往復回転により水平位置と落下位置との間で回動するように構成されている。レシーブ板８４の水平位置は、スライドファスナーＳＦを受け取る位置であり（図１５参照）、レシーブ板８４の落下位置は、レシーブ板８４を下方に傾けて、スライドファスナーＳＦを収納ボックス９０に移動させる位置である（図１６参照）。そして、レシーブ板８４を回動させてスライドファスナーＳＦを移動させるため、スライドファスナーＳＦは、その表側が上方を向いた状態にて収納ボックス９０に収納される。また、レシーブ板８４は、シュート板８３を滑り落ちたスライドファスナーＳＦを停止させる凸部８４ｂを有する。 The receiving plate 84 has one edge attached to a drive shaft 84a provided along the left-right direction, and is configured to rotate between a horizontal position and a drop position by reciprocal rotation of the drive shaft 84a.

(See FIG. 16). Since the slide fastener SF is moved by rotating the receive plate 84, the slide fastener SF is stored in the storage box 90 with its front side facing upward. Further, the receive plate 84 has a convex portion 84b that stops the slide fastener SF that has slid down the chute plate 83.
　収納ボックス９０は、不図示の駆動装置により前後方向に移動可能に設けられている。これにより、例えば、第１の列として第１～第３排出位置Ｐ１～Ｐ３のそれぞれに１束のスライドファスナーＳＦを収納した後、収納ボックス９０を前方に所定距離移動させて、第２の列として第１～第３排出位置Ｐ１～Ｐ３のそれぞれに１束のスライドファスナーＳＦを収納することができる。つまり、本実施形態では、収納ボックス９０内に３束のスライドファスナーＳＦの列を複数列作り出すことができる。 The storage box 90 is provided so as to be movable in the front-rear direction by a drive device (not shown). Thus, for example, after storing one bundle of slide fasteners SF at the first to third discharge positions P1 to P3 as the first row, the storage box 90 is moved forward by a predetermined distance to move to the second row. As a result, one bundle of slide fasteners SF can be stored in each of the first to third discharge positions P1 to P3. That is, in the present embodiment, a plurality of rows of three slide fasteners SF can be created in the storage box 90.
