(Step of moving the zipper slider that moves the first zipper slider 11 and the second zipper slider 12 to cause the fastener element 5 to be engaged)

When the first gap 6 of the fastener chain 1 is aligned with the cutting position G as shown in FIG. 9(a) and the time point cut at the first gap 6 as shown in FIG. 9(b), The zipper slider moving portion 29 is operated.

Thereby, as shown in FIG. 9(b), the first zipper slider 11 is moved toward the upper stopper 13, and the first zipper slider 11 is in contact with the upper stopper 13 as shown in FIG. 9(c).

Thus, the fastener elements 5 between the first zipper slider 11 and the second zipper slider 12 are in a engaged state.

As shown in Fig. 9(e), when the fastener chain 1 of the fastener tape 4 is cut at the second gap 7, the zipper slider holding portion 30 is operated.

Thereby, since the second zipper slider 12 is held so as not to move in the transport direction, the second zipper slider 12 is relatively opposed to the cannula 14 and the seat as the separable member 16 by the transport of the fastener chain 1 The tube 15 is moved, and as shown in Fig. 9(f), the second zipper slider 12 is in contact with the cannula 14, which is the separable member 16, and the seat tube 15.

Thus, since the sprocket 5 is all in the engaged state, the reverse zipper 10 shown in Fig. 2 can be formed.

(Zipper chain transport step until the fastener chain on the upstream side in the transport direction is transferred to the transport roller 23)

In each of the above steps, the fastener chain 1 is conveyed so as to be stretched by the transport roller 23 provided on the most downstream side of the transport path 21.

Therefore, as shown in FIG. 9(c), after the fastener tape 4 is cut at the first gap 6, the fastener chain 1-1 on the upstream side in the transport direction from the cut portion cannot be transported by the transport roller 23.

In the present invention, the chain transfer unit 31 transfers the fastener chain 1-1 on the upstream side in the transport direction from the cut portion shown in Fig. 9(c) toward the transport roller 23.

When the fastener chain 1-1 is transferred to the state shown in FIG. 9(d), the downstream side end of the fastener chain 1-1 in the conveyance direction reaches the conveyance roller 23.

As a result, as shown in FIG. 9( e ), the fastener chain 1-2 of the reverse type slide fastener 10 which is the chain belt 4 in which the second gap 7 is cut is conveyed by the transport roller 23 .

Then, as shown in FIG. 9(e), after the second gap 7 is cut, the fastener chain 1-3 on the upstream side in the transport direction from the cut portion indicated by the imaginary line is transferred to the transport by the chain transfer unit 31. The roller 23 is up.

Therefore, the fastener chain 1 is conveyed so that it may be extended by the conveyance roller 23, and the fastener chain 1 is conveyed by the tension.

The fastener chain 1 on the upstream side in the conveyance direction of the cut portion cut by the cutting portion 28 is transferred to the transport roller 23 by the chain transfer portion 31.

According to the method for manufacturing a reverse-opening slide fastener of the present invention, by continuously conveying the continuous fastener chain 1, void formation, reinforcing tape mounting, zipper slider mounting, upper stopper, separable member mounting, and zipper chain cutting are continuously performed. Thereby, the reverse zipper 10 having the first zipper slider 11, the second zipper slider 12, the upper stopper 13, and the separable member 16 can be manufactured.

Further, the reverse-opening zipper 10 can be automatically manufactured from the continuous fastener chain 1, so that the productivity of the reverse-opening zipper 10 is improved.

In the method of manufacturing the reverse-opening slide fastener 10 of the embodiment, the first air gap 6 and the second air gap 7 are formed by transporting the fastener chain 1, and the first air gap 6 and the second air gap 7 can be formed by one air gap forming portion 24.

In the manufacturing method of the reverse zipper 10 of the embodiment, the fastener chain 1 is conveyed, and the reinforcing tape 8 is attached to the fastener tape 8 of the first gap 6 and the second gap 7, so that one reinforcing belt mounting portion 25 can be used first.

The upper belt 13 is attached to the chain belt 4 of the gap 7, and the cannula 14 and the seat tube 15 as the separable member 16 are attached.

Next, the conveying roller 23, the cutting unit 28, the zipper slider moving portion 29, the zipper slider holding portion 30, and the chain transfer portion 31 will be described. In addition, the direction orthogonal to the conveyance direction of the fastener chain 1 is demonstrated as a width direction.

As shown in FIG. 10 and FIG. 11 , the base 40 includes a horizontal base 41 , a first vertical frame 42 that is provided on the downstream side of the base 41 in the transport direction and that is close to one end in the width direction, and an upstream side that is disposed in the transport direction of the base 41 and The second vertical frame 43 is adjacent to the other end in the width direction.

In the housing 40, the conveying roller 23, the slider holder holding portion 30, the cutting portion 28, the chain transfer portion 31, the gap detecting portion 32, and the reverse conveying roller 33 are sequentially disposed from the downstream side in the conveying direction toward the upstream side in the conveying direction. And a guide roller 34.

A conveying roller 23 is provided on the downstream side of the conveying direction of the base 40. The conveying roller 23 has a first driving roller 23a and a first pinch roller 23b.

The first drive roller 23a is rotatably attached to the first vertical frame 42 by a horizontal shaft (not shown).

The first motor 44 is attached to the first vertical frame 42, and the first drive roller 23a is rotated in the direction of the arrow by the first motor 44.

The first pinch roller 23b is in contact with the first drive roller 23a. The fastener chain 1 is held by the first drive roller 23a and the first pinch roller 23b, and the fastener chain 1 is conveyed by rotating the first drive roller 23a in the direction of the arrow.

The first pinch roller 23b faces away from the first driving roller 23a and A direction in which the driving roller 23a contacts is moved. For example, the first cylinder 45 is erected upward on the base 41, and the first bracket 46 is mounted on the first piston rod 45a of the first cylinder 45. The first pinch roller 23b is rotatably attached to the first bracket 46 by a horizontal shaft 47.

Thereby, the first pinch roller 23b is moved toward the first driving roller 23a together with the first bracket 46 by elongating the first piston rod 45a of the first cylinder 45.

By contracting the first piston rod 45a of the first cylinder 45, the first pinch roller 23b moves together with the first bracket 46 in a direction away from the first driving roller 23a.

The zipper slider holding portion 30 that holds the second zipper slider 12 includes a first holding body 50 and a second holding body 51 that faces the first holding body 50 in the vertical direction.

The first holding body 50 is fixedly attached to the first vertical frame 42, and the first holding body 50 is located above the transport path 21 of the zipper chain.

The second holding body 51 is located below the conveying path 21, and the second holding body 51 moves in the vertical direction in a direction approaching and away from the first holding body 50. For example, the second cylinder 52 is erected on the base 41, and the second piston rod 52a of the second cylinder 52 is coupled to the second holding body 51.

When the second piston rod 52a of the second cylinder 52 is extended, the second holding body 51 moves in a direction approaching the first holding body 50.

The second holding body 51 is moved in a direction away from the first holding body 50 by contracting the second piston rod 52a of the second cylinder 52.

The second holding body 51 is moved toward the first holding body 50, and is sandwiched by the lower surface 50a of the first holding body 50 and the upper surface 51a of the second holding body 51. The second zipper puller 12. Thereby, the second slider body 12 is held by the first holder 50 and the second holder 51 so as not to move in the transport direction, the width direction, and the vertical direction.

For example, the lower surface 50a of the first holding body 50 has a concave portion to be fitted to the upper portion of the second zipper slider 12. The lower surface of the second zipper slider 12 is pressed by the upper surface 51a of the second holding body 51, and the second zipper slider 12 is pressed into and held by the recess of the first holder 50. Thereby, the second zipper slider 12 is held and held by the first holding body 50 and the second holding body 51.

The cutting portion 28 includes a first cutter 55 and a second cutter 56.

The first cutter 55 is attached above the transport path 21 so as to move in the vertical direction.

The second cutter 56 is attached below the transport path 21 so as to move in the vertical direction. The second cutter 56 is located directly below the first cutter 55.

A third cylinder 57 is attached to the first vertical frame 42 in the vertical direction. A first cutter 55 is mounted on the third piston rod 57a of the third cylinder 57.

A fourth cylinder 58 is attached to the base 41 in the vertical direction. A second cutter 56 is mounted on the fourth piston rod 58a of the fourth cylinder 58.

The width of the first cutter 55 and the second cutter 56 is larger than the width of the pair of chain belts 4 of the fastener chain 1.

The third piston rod 57a of the third cylinder 57 is extended to lower the first cutter 55, and the fourth piston rod 58a of the fourth cylinder 58 is extended to raise the second cutter 56, thereby using the first cutter 55 and second cutter 56 will zipper chain 1 A pair of chain belts 4 are cut.

The chain transfer portion 31 has a fastener tape 4 that grips the fastener chain 1 or a gripper 60 that releases the grip of the fastener tape 4 of the fastener chain 1. The gripper 60 spans the first position on the upstream side in the transport direction from the cutting unit 28 and the second position on the downstream side in the transport direction from the transport roller 23, and reciprocates in the transport direction.

The gripper 60 moves in a direction approaching the fastener chain 1 and a direction away from the fastener chain 1 at the first position and the second position.

In this way, the fastener chain 1 of the fastener chain 1 which is cut by the cutting part 28 in the conveyance direction is conveyed to the downstream of the conveyance direction of the conveyance roller 23 by the clamper 60.

The chain transfer unit 31 has a first guide 61 that is attached to the other end in the width direction of the base 41 toward the conveyance direction.

The first moving body 62 is movably disposed along the first guide 61.

A second guide 63 facing the width direction is provided on the upper surface of the first moving body 62. The second movable body 64 is movably disposed along the second guide 63 in the width direction, and the plate 65 is horizontally attached to the upper surface of the second movable body 64.

A second bracket 66 is mounted on the plate 65, and a holder 60 is mounted on the second bracket 66.

The holder 60 has a pair of upper and lower grip claws (not shown). When the upper and lower pair of gripping claws are swung in the approaching direction, the gripper 60 performs the gripping operation, and the upper and lower gripping claws are swung in the direction away from each other, whereby the gripper 60 performs the grip releasing operation.

The transfer operation of the fastener chain 1 by the chain transfer unit 31 will be described.

The first moving body 62 is moved to the upstream side in the conveying direction, and the gripper 60 is placed in the grip release state at the first position.

The second moving body 64 is moved in the direction approaching the fastener chain 1 along the second guide 63 such that one gripping claw is above the chain belt 4 and the other gripping claw is below the chain belt 4.

The pair of gripping claws are swung in the approaching direction, so that the gripper 60 grips the chain belt 4.

The first moving body 62 is moved along the first guide 61 toward the downstream side in the conveying direction, thereby moving the gripper 60 to the second position.

Thereby, the held fastener chain 1 is transferred to the downstream side in the conveyance direction of the conveyance roller 23.

The pair of gripping claws are swung in a direction away from each other, so that the gripper 60 releases the grip of the chain belt 4.

The second moving body 64 is moved along the second guide 63 in a direction away from the fastener chain 1, whereby the holder 60 faces away from the fastener chain 1.

The first moving body 62 is moved along the first guide 61 toward the upstream side in the conveying direction, thereby moving the gripper 60 to the first position.

That is, the holder 60 moves along the trajectory of the planar rectangular shape. When the fastener chain 1 is cut by the cutting unit 28, the fastener chain 1 on the upstream side in the transport direction of the cut portion is transferred to the downstream side in the transport direction of the transport roller 23 by the gripper 60.

The gap detecting unit 32 detects the gap of the fastener chain 1 transported along the transport path 21 toward the cutting unit 28 on the upstream side in the transport direction of the cutting unit 28, and outputs a detection signal.

The gap detecting portion 32 has a pair of guides 70 in the width direction through which the fastener chain 1 passes.

The pair of guides 70 are swingable along the horizontal plane by the vertical shaft 71, and the pair of guides 70 are swing-applied in a direction in which the opposing inner side surfaces 72 approach by a spring (not shown), so that the pair of guides 70 are Close to the state.

If the pair of guides 70 are in the approaching state, the detector 73 outputs a detection signal.

The detector 73 is mounted on a third bracket 74 that is erected on the base 41. A detecting lever 75 is attached to a guide member 70 such that the detecting piece 75a of the detecting lever 75 faces the detector 73.

If the pair of guides 70 are in the approaching state, the detecting piece 75a is close to the detector 73, and the detector 73 outputs a detection signal. That is, the detector 73 is of a non-contact type.

If the pair of guides 70 are swung in a direction away from the inner side surface 72 against the spring force, the detecting piece 75a faces away from the detector 73. Thereby, the detector 73 does not output a detection signal.

As shown in Fig. 12, the inner surface 72 of the guide 70 includes a first surface 72a at the upstream end in the transport direction, a second surface 72b on the upstream side in the transport direction, a third surface 72c on the downstream side in the transport direction, and a downstream end in the transport direction. 72d on all sides.

The first face 72a has a hook shape and is shaped between the first faces 72a of the pair of guides 70. A wide first gap 76a.

The second surface 72b has a linear shape along the conveying direction, and a narrow second gap 76b is formed between the second surfaces 72b of the pair of guides 70.

The third surface 72c is inclined with respect to the conveyance direction, and the third gap 76c between the third faces 72c of the pair of guides 70 is gradually narrowed toward the downstream side in the conveyance direction.

The fourth surface 62d has a hook shape, and a wide fourth gap 76d is formed between the fourth faces 72d of the pair of guides 70.

When the pair of guides 70 are in the approaching state, the width of the second gap 76b is the same as the width of the fastener elements 5 of the fastener chain 1.

The pair of guides 70 has a groove 77 that is open on the inner side surface 72. When the pair of guides 70 are in the approaching state, the width between the pair of grooves 77 is the same as the width of the fastener chain 1.

The zipper chain 1 is shown in Fig. 13, and the chain belt 4 is inserted into the groove 77 of the guide member 70, and the sprocket 5 is inserted between the inner side faces 72 of the pair of guide members 70.

The third surface 72c of the inner side surface 72 of the guide 70 is in contact with both end faces of the sprocket 5 in the width direction, whereby the pair of guides 70 swing in the direction away from the inner side surface 72 around the shaft 71, and a pair of guides 70 is in a separated state.

Thereby, the detecting piece 75a of the detecting lever 75 is separated from the detector 73, and thus the detector 73 does not output a detection signal.

As shown in FIG. 11, the fastener chain 1 is conveyed along the pair of guides 70. At this time, the pair of guides 70 are in a spaced state.

Moreover, if the second gap 7 of the zipper chain 1 from which the sprocket 5 is removed reaches the pair of guides 70, and the second gap 7 moves to the third gap 76c, the guide The third face 72c of the inner side surface 72 of the 70 is not in contact with the fastener element 5.

Thereby, the pair of guides 70 are swung in the direction in which the inner side surface 72 approaches, and the pair of guides 70 are in the approaching state shown in FIG.

If the pair of guides 70 are in the approaching state, as shown in FIG. 12, the detecting piece 75a of the detecting lever 75 is close to the detector 73, and the detector 73 outputs a detection signal.

The detection signal output from the detector 73 is used to detect that the second gap 7 of the fastener chain 1 has reached the pair of guides 70.

The gap detecting portion 32 has a third guide 80. The third guide 80 is mounted at a position close to the width direction of the base 41 so as to be located directly below the transport path 21.

The third moving body 81 is movably disposed along the third guide 80, and the post 82 is attached to the third moving body 81. The horizontal plate 83 is horizontally mounted on the upper portion of the column 82, and the pair of guides 70 are swingably attached to the upper surface of the horizontal plate 83 by the shaft 71.

Therefore, by moving the third movable body 81 along the third guide 80, the gap detecting portion 32 spans the gap detecting position on the upstream side in the conveying direction shown in FIG. 11 and the downstream side in the conveying direction close to the cutting portion 28. The zipper pulls the position and moves.

Thereby, the gap detecting unit 32 constitutes the slider moving portion 29 that moves the first slider slider 11 of the fastener chain 1 as will be described later.

The reverse conveying roller 33 includes a second driving roller 33a and a second pinch roller 33b.

The second drive roller 33a is rotatably attached to the second vertical frame 43 by a horizontal shaft. The second drive roller 33a is rotated by the second motor 84 attached to the second vertical frame 43.

The second pinch roller 33b is rotatably attached to the arm portion 85. The arm portion 85 is swingably attached to the second vertical frame 43 in the vertical direction by a horizontal shaft, and the arm portion 85 is swung upward by the spring 86.

Thereby, the second pinch roller 33b is crimped to the second drive roller 33a.

The guide roller 34 is rotatably attached to the second vertical frame 43 by a horizontal shaft.

Thereby, the fastener chain 1 is guided by the guide roller 34 so as not to be deviated in the width direction. Further, the fastener chain 1 is continuously conveyed to the transport roller 23 via the reverse transport roller 33 and the pair of guides 70, and the fastener chain 1 is transported by the transport roller 23. In other words, the transport roller 23, the chain transfer unit 31, and the reverse transport roller 33 are transport units that transport the fastener chain 1 along the transport path 21.

The cutting operation of the fastener chain 1 will be described.

The fastener chain 1 is conveyed by the conveying roller 23. At this time, the pair of guides 70 are in a spaced state as shown in FIG.

If the first gap 6 of the fastener chain 1 reaches the third gap 76c of the pair of guides 70, the pair of guides 70 come into a close state as shown in FIG.

Thereby, the detector 73 outputs a detection signal. The detection signal output from the detector 73 is transmitted to the controller 90.

The controller 90 outputs a deceleration command to the first motor 44, and the first motor 44 decelerates. Thereby, the conveyance speed of the fastener chain 1 is decelerated.

Further, by transporting the fastener chain 1, the first gap 6 passes through the third gap 76c of the pair of guides 70, and the fastener element 5 reaches the third gap 76c. The pair of guides 70 are separated from each other by the fastener elements 5, and the detector 73 does not output a detection signal. Thereby, it can be detected that the first gap 6 of the fastener chain 1 has passed through the pair of guides 70.

Further, in the chain belt 4 of the first gap 6 of the fastener chain 1, the cannula 14 as the separable member 16, and the seat tube 15 are moved to the first surface of the lower surface of the first cutter 55 of the cutting portion 28. At the time of the notch portion 55a and the second notch portion 56a of the upper surface of the second cutter 56, the first motor 44 is stopped to stop the rotation of the conveying roller 23, and the fastener chain 1 is stopped.

For example, in the controller 90, the time from when the detection signal is transmitted until the movement of the fastener chain 1 to the position is set, the controller 90 outputs a stop signal of the first motor 44 after the set time elapses, and stops the rotation of the conveying roller 23. Thereby, the zipper chain 1 is stopped.

In a state where the zipper chain 1 has been stopped, as shown in FIG. 14, the insertion tube 14 as the detachable member 16 of the fastener chain 1 and the seat tube 15 are located at the first notch portion 55a and the first portion of the first cutter 55. The first step 55c of the blade portion 55b and the second notch portion 56a of the second cutter 56 and the second step 56c of the second blade portion 56b are located on the downstream side in the conveying direction.

The first zipper slider 11 of the zipper chain 1 passes through the guide 70, and the first zipper slider 11 is located at the downstream side in the conveying direction of the guide 70.

Next, an operation of moving the first slider slider 11 of the fastener chain 1 to the upper stopper 13 will be described.

The width of the first zipper slider 11 of the zipper chain 1 is larger than the width of the sprocket 5, so that when the first zipper slider 11 passes the third gap 76c of the pair of guides 70, the pair of guides 70 are as shown in FIG. The approaching state shown swings in a direction away from the inner side surface 72.

If the first zipper slider 11 passes the third gap 76c of the pair of guides 70, the pair of guides 70 swing in the direction in which the inner side surface 72 approaches, whereby the third surface 72c of the guide 70 is as shown in FIG. It is in contact with the sprocket 5, and the pair of guides 70 are in a close state.

Therefore, the first slider slider 11 that has passed through the pair of guides 70 cannot move to the upstream side in the conveyance direction by the gap between the inner side surfaces 72 of the pair of guides 70.

The controller 90 outputs a rotation command of the second motor 84 after the zipper chain 1 has stopped, and drives the second motor 84, thereby rotating the second drive roller 33a in the direction of the arrow.

Thereby, the first zipper slider 11 of the fastener chain 1 enters into the fourth gap 76d of the pair of guides 70 as shown in Fig. 15, and the first zipper slider 11 is held by the pair of guides 70.

In the state shown in Fig. 15, the pair of guides 70 (the gap detecting portion 32) are located at the gap detecting position.

By moving the third movable body 81 along the third guide 80 to the downstream side in the conveyance direction, the pair of guides 70 are moved to the downstream side in the conveyance direction.

When the pair of guides 70 are moved, the first zipper slider 11 moves along the sprocket 5 toward the downstream side in the transport direction.

The pair of guides 70 are moved to the position where the zipper slider moves, whereby the first zipper slider 11 is moved until it comes into contact with the upper stopper 13 (see FIG. 9(b)).

When the first zipper slider 11 is moved, the zipper chain 1 sometimes moves along with the first zipper slider 11, and in this case, as shown in FIG. 10, the transport path 21 is transported over the pair of guides 70. A clamper 91 is provided at the upstream side of the direction. by The jig 91 holds the fastener chain 1 so that the fastener chain 1 does not move to the downstream side in the conveyance direction by the jig 91.

After the pair of guides 70 are moved to the position where the sliders are moved, the third movable body 81 is moved along the third guide 80 toward the upstream side in the conveyance direction, whereby the pair of guides 70 are positioned at the gap detection position. At this time, the first zipper slider 11 does not move, and the first zipper slider 11 is held at a position in contact with the upper stopper 13.

That is, the gap detecting portion 32 also serves as the zipper slider moving portion 29.

Next, an operation of cutting the chain belt 4 of the first gap 6 of the fastener chain 1 will be described.

The controller 90 outputs a rotation command of the second motor 84 to drive the second motor 84, thereby rotating the second drive roller 33a in the direction of the arrow. The fastener chain 1 is moved to the upstream side in the conveyance direction, and the insertion tube 14 and the seat tube 15 as the separable member 16 attached to the fastener tape 4 of the first gap 6 of the fastener chain 1 are abutted to the first side as shown in FIG. The first step 55c of the cutter 55 and the second step 56c of the second cutter 56.

Thereby, the cutting position of the fastener chain 1 can be positioned with high precision by the 1st cutter 55 and the 2nd cutter 56.

At this time, the first cutter 55 extends the third piston rod 57a of the third cylinder 57 and moves in a direction approaching the transport path 21, and the first blade portion 55b of the first cutter 55 approaches the chain belt 4. The second cutter 56 extends the fourth piston rod 58a of the fourth cylinder 58 and moves in a direction approaching the transport path 21, and the second blade portion 56b of the second cutter 56 approaches the chain belt 4.

The first cutter 55 and the second cutter 56 are moved in a direction close to the transport path 21, and the first blade portion 55b of the first cutter 55 and the second blade portion 56b of the second cutter 56 are used to cut the first A chain belt 4 having a gap 6 (refer to Fig. 9(c)).

After the chain belt 4 is cut, the first cutter 55 and the second cutter 56 are moved in a direction away from the transport path 21.

After the chain belt 4 is cut, the fastener chain 1 on the downstream side in the conveyance direction from the cut portion is conveyed by the conveyance roller 23 and discharged.

After the chain belt 4 is cut, the fastener chain 1-1 on the upstream side in the transport direction of the cut portion is transferred to the transport roller 23 by the chain transfer unit 31 as described above (see FIG. 9(c)).

In other words, the gripper 60 of the chain transfer unit 31 moves along a rectangular track of the plane, and the fastener tape 60 of the fastener chain 1-1 is gripped by the gripper 60 and conveyed to the transport roller 23.

At this time, the first piston rod 45a of the first cylinder 45 is contracted to move the first pinch roller 23b in a direction away from the first driving roller 23a, between the first driving roller 23a and the first pinch roller 23b. A gap is formed.

The fastener chain 1-1 which is conveyed by the holder 60 and moved is moved to a downstream side in the conveyance direction of the conveyance roller 23 by the gap between the first drive roller 23a and the first pinch roller 23b.

Then, the first piston rod 45a of the first cylinder 45 is extended to move the first pinch roller 23b in a direction approaching the first driving roller 23a, and is sandwiched by the first driving roller 23a and the first pinch roller 23b. Hold the zipper chain 1-1.

Further, before the fastener tape 4 of the first gap 6 of the fastener chain 1 is cut, the fastener tape 4 of the fastener chain 1 can be held by the holder 60 of the chain transfer portion 31.

The operation of moving the second zipper slider 12 of the fastener chain 1 will be described.

The fastener chain 1-2 (see FIG. 9(e)) of the fastener tape 4 in which the second gap 7 has been cut of the fastener chain 1 is conveyed and discharged by the conveyance roller 23.

At this time, the second zipper slider 12 is held by the first holding body 50 of the zipper slider holding portion 30 and the second holding body 51.

In this state, the fastener chain 23 is transported by the transport roller 23, whereby the second zipper slider 12 is relatively movable in the direction of the cannula 14 and the seat tube 15 as the separable member 16, and the second zipper slider 12 is in contact with the cannula 14 and the seat tube 15 as the separable member 16.
