Description of the Related Art As a manufacturing apparatus for manufacturing a sheet-like product, an apparatus that performs a relaxation process by reducing the sheet-like product in the width direction and the longitudinal direction (transfer direction) is known (for example, see Patent Document 1). In this sheet-like material transfer device, a first transfer region, a decelerating transfer region and a second transfer region are provided along a transfer path for transferring the sheet-like material, and these first transfer region, decelerating transfer region and second transfer region are provided.

The transfer chain mechanism is disposed on both sides of the transfer path, the transfer chain mechanism on one side clips and transfers one side of the sheet-like material, and the other transfer chain mechanism moves on the other side of the sheet-like material. Clip and transport.

  The transfer chain mechanism has a clip connecting portion for clipping the sheet-like material and a connection connecting portion for connecting adjacent clip connecting portions, and the connection connecting portion is configured to be bent inward in the transfer direction. ing. Since the connection connecting portion is bent, the length in the transfer direction of the connection connecting portion changes, and in the state where the connection connecting portion is bent large (or small), the length of the transfer method is large (or Shrink)

  In this sheet-like material transfer device, the connection connecting portion of the transfer chain mechanism is held in a normal state (unbent state) in the first transfer region, and the connection connection is in a predetermined bent state in the second transfer region. It is held and held in a contracted state, and in the decelerating transfer area, this connection connecting portion is bent inward gradually from the normal state to the contracted state. Accordingly, the sheet-like material clipped (that is, so-called chucking) to the clip connecting portion of the transfer chain mechanism is transferred at a predetermined transfer speed in the first transfer area and gradually decelerated from the predetermined transfer speed in the decelerating transfer area. In the second transfer zone, the sheet-like material is reduced in the longitudinal direction (transfer direction) and is reduced in this way while being transferred at a reduced low transfer speed and transferred through the reduced transfer zone. Thus, a relaxation process in the longitudinal direction can be performed on the sheet-like material.

  Further, in the decelerating transfer area 10 between the first transfer area 8 and the second transfer area 12, the spiral protrusion 44 of the drive rotating shaft 42 is a part of the first clip connecting portion 74 of the first chain unit 72. The first chain unit 72 is moved while gradually decreasing from the first transfer speed to the second transfer speed, as will be described later.

  The second transfer chain mechanism 16 will be described with reference to FIGS. 4 and 5 together with FIGS. 1 and 2. The second transfer chain mechanism 16 is formed by connecting a number of second chain units 82 in an endless manner.

It is disposed endlessly through the zone 10 and the second transfer zone 12, moved in the first transfer zone 8 by the first drive means at the first transfer speed, and gradually decelerated in the deceleration transfer zone 10 by the deceleration drive means. In the second transfer zone 12, the second drive means 12 is moved at the second transfer speed. The second transfer chain mechanism 16 is disposed between the third sprocket 28 and the fourth sprocket 29 through the first transfer zone 8, and moves in the first transfer zone 8 at the first transfer speed by the first driving means.

Thus, the first and second chain links 80, 85 are rotated. In this state, the length of the first connection connecting portion 76 in the transfer direction (in other words, the interval between the adjacent first clip connecting portions 74) is reduced.

  More specifically, as shown in FIG. 7, when the first chain link 80, the intermediate connection link 90, and the second chain link 85 extend linearly, the length of the first chain unit 72 is the longest, The pitch of the first clip connecting portion 74 is L1 (see FIG. 7). As the driven roller 96 moves upward (outside the first transfer chain mechanism 14) in FIG. 7 from such a state, the first and second chain links 80 and 85 of the first connection connecting portion 76 are swung, As the turning angle increases, the length of the first chain unit 72 in the transfer direction is gradually shortened and reduced. In the state where the driven roller 96 is moved to the uppermost position in FIG. 7 (that is, the state shown in FIG. 8), the first and second chain links 80 and 85 are turned approximately 90 degrees, and the first chain unit 72 The length in the transport direction is reduced to the minimum, and the pitch of the first clip connecting portion 74 is L2 (see FIG. 8), and this pitch interval L2 is half of the pitch interval L1 (L2 = L1 / 2).

  In the sheet-like material transfer device 4a (4b), a pitch reducing member 100 is disposed corresponding to the driven roller 96 of the first chain unit 72 (see FIGS. 5 and 6). The pitch reduction member 100 extends from the downstream side of the first transfer zone 8 (the upstream side of the deceleration transfer zone 10) through the deceleration transfer zone 10 and the second transfer zone 12 inside the first transfer chain mechanism 14, and further includes a fifth The peripheral portion of the procket 58 extends to the vicinity of the first sprocket 26, and its upstream side portion 102 extends linearly away from the first transfer chain mechanism 14, and the outer inclined portion 104 following this upstream side portion 102 is The intermediate portion 106 that extends outwardly toward the transfer direction so as to approach the first transfer chain mechanism 14 and overlaps the first transfer chain mechanism 14 so as to partially overlap the first transfer chain mechanism 14. It extends around the outer peripheral edge of the fifth sprocket 58 and extends toward the first sprocket 26. Further, the inner inclined portion 108 (the portion corresponding to the outer inclined portion 104) following the intermediate portion 106 extends inwardly in the direction opposite to the transfer direction so as to be away from the first transfer chain mechanism 14, and further to the inner portion. A downstream side portion 110 (a portion corresponding to the upstream side portion 102) following the inclined portion 108 extends linearly away from the first transfer chain mechanism 14.

  The pitch reduction member 100 acts on the driven roller 96 of each first connection connecting portion 76 of the first transfer chain mechanism 14 so as to reduce the length of the first chain unit 72 in the transfer direction. That is, the upstream side portion 102 and the downstream side portion 110 of the pitch reducing member 100 do not substantially act on the first connection connecting portions 76, and the driven roller 96 is placed on the side surfaces of the upstream side portion 102 and the downstream side portion 110. Accordingly, the first chain unit 72 is in a state in which the first connection connecting portion 76 is linear (that is, the longest in the transfer direction) as shown in FIG. Moved.

  Further, the outer inclined portion 104 of the pitch reducing member 100 acts more greatly on the driven roller 96 of the first connection connecting portion 76 toward the downstream side in the transfer direction, and accordingly, the first and second chain links 80, When the first and second chain links 80 and 85 are turned, the length of the first connection connecting portion 76 (that is, the first chain unit 72) in the transfer direction is reduced. Then, the closer to the second transfer area 12, the more the length in the transfer direction is greatly reduced.

Accordingly, the first and second chain links 80 and 85 are largely swung outward, so that the length of the first connection connecting portion 76 (that is, the first chain unit 72) in the transfer direction is the smallest. The first chain unit 72 moves in a state where the length in the transfer direction is reduced by half.

  Furthermore, the inner inclined portion 108 of the pitch reducing member 100 releases the action state of the first connection connecting portion 76 to the driven roller 96 as it goes to the downstream side in the movement direction indicated by the arrow 112. The first and second chain links 80 and 85 are turned so as to return to the inside, and the first and second chain links 80 and 85 are turned so that the first connection connecting portion 76 (that is, the first chain unit 72). The length in the transfer direction is restored to the original, and the reduced state is canceled so that the length in the transfer direction returns to the original length as the downstream side portion 110 is approached.

  In this embodiment, since the first and second chain links 80 and 85 of the first connection connecting portion 76 are turned to 90 degrees, the length of the first chain unit 72 in the transfer direction is reduced to half. However, by adjusting the turning angle of the first and second chain links 80 and 85 (in other words, adjusting the position of the pitch reducing member 100 acting on the dependent roller 96 of the first connection connecting portion 76), The length in the transfer direction of one chain unit 72 (so-called reduction ratio) can be adjusted steplessly.

  In this embodiment, the pitch reducing member 100 is disposed inside the first transfer chain mechanism 14, and the first and second chain links 80 and 85 are turned and reduced by the pitch reducing member 100.

It is configured symmetrically about the transfer direction.

  In the second embodiment, the sheet-like material transfer device 304a (304b) extends through the first transfer area 8, the decelerating transfer area 10 and the second transfer area 12, and the sheet-like material S is transferred to the first transfer area 8, It is transferred as required in the transfer direction indicated by arrow 306 through the decelerating transfer zone 10 and the second transfer zone 12. The first transfer chain mechanism 314 of the sheet-like material transfer device 304a (304b) is inclined and extended outward toward the downstream side in the transfer direction in the width expansion transfer area 320 of the first transfer area 8, and this width expansion. On the upstream side of the transfer zone part 320 (that is, the upstream side part of the first transfer zone 8), the sheet-like material extends linearly so that the width becomes W1, and the downstream side thereof (that is, the first transfer zone 8 of the first transfer zone 8). In the downstream side, the decelerating transfer area 10 and the second transfer area 12), the sheet-like material S extends linearly so that the width is W2. In addition, the second transfer chain mechanism 316 of the sheet-like material transfer device 304a (304b) is inclined and extended outward toward the downstream side in the transfer direction in the width-enlarging transfer region 320 of the first transfer region 8. On the upstream side of the width-enlarged transfer region portion 320 (that is, the upstream portion of the first transfer region 8), the sheet-like material extends linearly so that the width is W1, and the downstream side (that is, the first transfer region). 8 on the downstream side) extends in a straight line so that the width of the sheet S is W2. In addition, about the 1st and 2nd transfer chain mechanism 314,316, the thing of the structure similar to the thing of the above-mentioned 1st Embodiment can be used.

Since the sheet-like object S held by the clips (so-called chucking holding) is pulled outward as it moves in the transfer direction because it moves to the outside, The sheet S is expanded and expanded in the width direction. Then, in the subsequent decelerating transfer area 10, the first transfer chain mechanism 314 is gradually reduced by the action of the drive rotation shaft 42, whereby the sheet-like material S expanded in the width direction is reduced in the transfer direction.

  In the third embodiment shown in FIG. 15, the sheet-like material transfer devices 304 a and 304 b extend through the first transfer area 8, the decelerating transfer area 10, and the second transfer area 12, and the sheet-like object S is in the first transfer area. 8.

Further, in the reduced width transfer area 322 of the second transfer area 12, the first transfer chain mechanism 314 of the sheet-like material transfer device 304 a (304 b) extends inwardly toward the downstream side in the transfer direction. . Other configurations in the third embodiment may be substantially the same as those in the second embodiment described above.

  When such sheet-like material transfer devices 304a and 304b are used, in the width-enlarged transfer area 310 of the first transfer area 8, the first and second transfer chain mechanisms 314 and 316 are directed downstream in the transfer direction. Since the sheet-like object S held by the clips (so-called chucking holding) is pulled outwards as it is moved in the transfer direction as described above, the width-enlarged transfer area portion is moved to the outside. During the transfer of 310, the width of the sheet S is expanded and expanded from W1 to W2.

  In the decelerating transfer area 10, the first transfer chain mechanism 314 is gradually moved by the action of the drive rotation shaft 42, whereby the sheet-like material S expanded in the width direction is reduced in the transfer direction, and the subsequent first 2 In the reduced width transfer area portion 322 of the transfer area 12, the first transfer chain mechanism 314 moves inward toward the downstream side in the transfer direction, so that the sheet S held by the first transfer chain mechanism 314 is clipped. The width is reduced inward with movement in the transfer direction so that the width is reduced from W2 to W3, and after being reduced in the transfer direction, it is also reduced in the width direction.

Since the chain mechanisms 314 and 316 extend and move outward toward the downstream side in the transfer direction, the sheet-like object S held by the clips (so-called chucking holding) is the same as described above. With the movement in the transfer direction, the sheet is pulled outward, and the width of the sheet-like material S is expanded and expanded from W1 to W2 while the width-enlarged transfer area 310 is transferred.

  And in the 1st width reduction transfer area part 324 of the deceleration transfer area 10, the 1st transfer chain mechanism 314 inclines and extends inward toward the transfer direction downstream side, and the drive rotating shaft 42 faces the transfer direction.

  The fifth and sixth drive sources 62 and 64 are rotated so as to have the same rotation speed. When the fifth and sixth drive sources 62 and 64 are rotated, the fifth and sixth sprockets 54 and 56 are moved in a predetermined direction. As a result, the first transfer chain mechanism 14 is moved at the second transfer speed, as will be described later, and the fifth and sixth drive sources 62 and 64, the fifth and sixth rotating shafts 54 and 56 are moved. In addition, the fifth and sixth sprockets 58 and 60 constitute second drive means for moving the first transfer chain mechanism 14 at the second transfer speed. Note that the fifth drive source 62 (or the sixth drive source 64) is omitted, and the drive force from the sixth drive source 64 (or the fifth drive source 62) is supplied via the drive transmission mechanism (not shown). The fifth sprocket 58 (or the sixth sprocket 60) may be driven by being transmitted to the fifth rotation shaft 54 (or the sixth rotation shaft 56).

  Next, the first transfer chain mechanism 14 will be described with reference to FIGS. 3 and 5 together with FIGS. The illustrated first transfer chain mechanism 14 is configured by connecting a number of first chain units 72 in an endless manner, and each first chain unit 72 has a first clip connecting portion for clipping the sheet-like object S. 74 and a first connection connecting portion 76 connected to the first clip connecting portion 74, and the first connection connecting portion 76 connects the adjacent first clip connecting portions 74.

The first transfer chain mechanism 14 includes a second sprocket 27 attached to the second rotating shaft 23, a first sprocket 26 attached to the first rotating shaft 22, and a sixth sprocket attached to the sixth rotating shaft 56. 60 and the fifth sprocket 58 mounted on the fifth rotating shaft 54 act so as to bite, and the first transfer chain mechanism 14 is moved by this action. In the first transfer zone 8, the first chain unit 72 is moved at the first transfer speed as will be described later by the action of the first and second sprockets 26, 27, and in the second transfer zone 12, the fifth sprocket is moved. By the action of 58 and the sixth sprocket 60, the first chain unit 72 is moved at a second transfer speed lower than the first transfer speed, as will be described later.

  Further, in the decelerating transfer area 10 between the first transfer area 8 and the second transfer area 12, the spiral protrusion 44 of the drive rotating shaft 42 is a part of the first clip connecting portion 74 of the first chain unit 72. The first chain unit 72 is moved while gradually decreasing from the first transfer speed to the second transfer speed, as will be described later.

  The second transfer chain mechanism 16 will be described with reference to FIGS. 4 and 5 together with FIGS. 1 and 2. The second transfer chain mechanism 16 is formed by connecting a number of second chain units 82 in an endless manner. Each second chain unit 82 is configured to have a second clip connecting portion 84 for clipping the sheet-like object S (in order to clarify the distinction from the first clip connecting portion 74 of the first transfer chain mechanism 14). 4 to 6) and a second connection connecting portion 86 connected to the second clip connecting portion 84, and the second connection connecting portion 86 is adjacent to the second clip. The connecting portion 84 is connected. The second chain unit 82 (that is, the second clip connecting portion 84 and the second connection connecting portion 86) will also be described later.

  The second transfer chain mechanism 16 acts so that the third sprocket 28 and the fourth sprocket 29 are engaged, and the second transfer chain mechanism 16 is moved by this action. In the first transfer zone 8, the second transfer chain mechanism 16 moves at a first transfer speed that is the same as the transfer speed of the first transfer chain mechanism 14 as described later by the action of the third and fourth sprockets 28 and 29. Is done.

In the sheet-like material transfer device 4a (4b), as shown in FIGS. 3 to 6, the first transfer chain mechanism 14 is provided between the second sprocket 27 and the fifth sprocket 58, the first transfer area 8, and the reduced-speed transfer. It is disposed endlessly through the zone 10 and the second transfer zone 12, moved in the first transfer zone 8 by the first drive means at the first transfer speed, and gradually decelerated in the deceleration transfer zone 10 by the deceleration drive means. In the second transfer zone 12, the second drive means 12 is moved at the second transfer speed. The second transfer chain mechanism 16 is disposed between the third sprocket 28 and the fourth sprocket 29 through the first transfer zone 8, and moves in the first transfer zone 8 at the first transfer speed by the first driving means. Is done. In the first transfer area 8, the second transfer chain mechanism 16 is moved in synchronization with the first transfer chain mechanism 14 described above, and the second clip connecting portion 84 of the second transfer chain mechanism 16 is moved to the first transfer chain. The mechanism 14 is moved between the adjacent first clip connecting portions 74 of the mechanism 14 (see FIGS. 5 and 6).

  With this configuration, in the first transfer area 8, the sheet S is clipped to the first and second clip connecting portions 74 and 84 of the first and second transfer chain mechanisms 14 and 16 (so-called chatting). The second transfer chain mechanism 16 is disengaged from the decelerating transfer area 10 and the second transfer area 12 on the downstream side of the first transfer area 8, and the sheet S is In the decelerating transfer zone 10, the clip is clipped to the first clip connecting portion 74 of the first transfer chain mechanism 14 and decelerated and transferred, and in the second transfer zone, it is clipped to the first clip connecting portion 74 and transferred at the second transfer speed. Then, the sheet-like object S is reduced by the reduced-speed transfer in the reduced-speed transfer area 10, and the relaxation process in the longitudinal direction (transfer direction) can be performed on the sheet-like object S by this reduction process. .

  Next, the first transfer chain mechanism 14 and a specific configuration related thereto will be described mainly with reference to FIGS. The first chain unit 72 of the first transfer chain mechanism 14 includes a first clip connecting portion 74 and a first connection connecting portion 76, and the first connection connecting portion 76 is configured so that the interval in the transfer direction can be reduced. Yes. The first connection connecting portion 76 will be described with reference to FIGS. 7 and 8. The first connection connecting portion 76 includes the first clip connecting portion 74 (see FIGS. 7 and 8) of one adjacent first chain unit 72. In FIG. 7 and FIG. 8, the first chain link 80 pivotally coupled to the first chain unit 72 via the coupling shaft 78 and the first clip coupling portion 74 of the other adjacent first chain unit 72 (for example, A second chain link 85 that is pivotably coupled to the first chain link 80 via a coupling shaft 83, one end side is pivotally coupled to the first chain link 80 via a coupling shaft 86, and the other end side is a coupling shaft 88. And an intermediate connection link 90 rotatably connected to the second chain link 85. A projecting portion 92 projecting to the back side (inner side in FIGS. 5 and 6) is provided at an intermediate portion of the intermediate connection link 90 of the first connection connecting portion 76, and a support shaft 94 is provided on the projecting portion 92. The follower roller 96 is rotatably supported by the support shaft 94.

Since it is configured in this manner, as can be easily understood by comparing FIG. 7 and FIG. 8, the first roller link 80 is moved upward in FIG. 7 is rotated counterclockwise in FIG. 7, and the second chain link 85 is rotated clockwise about the connecting shaft 83, and thus the first and second chain links 80, 85 are rotated. In this state, the length of the first connection connecting portion 76 in the transfer direction (in other words, the interval between the adjacent first clip connecting portions 74) is reduced.

  More specifically, as shown in FIG. 7, when the first chain link 80, the intermediate connection link 90, and the second chain link 85 extend linearly, the length of the first chain unit 72 is the longest, The pitch of the first clip connecting portion 74 is L1 (see FIG. 7). As the driven roller 96 moves upward (outside the first transfer chain mechanism 14) in FIG. 7 from such a state, the first and second chain links 80 and 85 of the first connection connecting portion 76 are swung, As the turning angle increases, the length of the first chain unit 72 in the transfer direction is gradually shortened and reduced. In the state where the driven roller 96 is moved to the uppermost position in FIG. 7 (that is, the state shown in FIG. 8), the first and second chain links 80 and 85 are turned approximately 90 degrees, and the first chain unit 72 The length in the transport direction is reduced to the minimum, and the pitch of the first clip connecting portion 74 is L2 (see FIG. 8), and this pitch interval L2 is half of the pitch interval L1 (L2 = L1 / 2).

In the sheet-like material transfer device 4a (4b), a pitch reducing member 100 is disposed corresponding to the driven roller 96 of the first chain unit 72 (see FIGS. 5 and 6). The pitch reduction member 100 extends from the downstream side of the first transfer zone 8 (the upstream side of the deceleration transfer zone 10) through the deceleration transfer zone 10 and the second transfer zone 12 inside the first transfer chain mechanism 14, and further includes a fifth The peripheral portion of the sprocket 58 extends to the vicinity of the first sprocket 26, and the upstream side portion 102 extends linearly away from the first transfer chain mechanism 14, and the outer inclined portion 104 following the upstream side portion 102 is The intermediate portion 106 that extends outwardly toward the transfer direction so as to approach the first transfer chain mechanism 14 and overlaps the first transfer chain mechanism 14 so as to partially overlap the first transfer chain mechanism 14. It extends around the outer peripheral edge of the fifth sprocket 58 and extends toward the first sprocket 26. Further, the inner inclined portion 108 (the portion corresponding to the outer inclined portion 104) following the intermediate portion 106 extends inwardly in the direction opposite to the transfer direction so as to be away from the first transfer chain mechanism 14, and further to the inner portion. A downstream side portion 110 (a portion corresponding to the upstream side portion 102) following the inclined portion 108 extends linearly away from the first transfer chain mechanism 14.

  The pitch reduction member 100 acts on the driven roller 96 of each first connection connecting portion 76 of the first transfer chain mechanism 14 so as to reduce the length of the first chain unit 72 in the transfer direction. That is, the upstream side portion 102 and the downstream side portion 110 of the pitch reducing member 100 do not substantially act on the first connection connecting portions 76, and the driven roller 96 is placed on the side surfaces of the upstream side portion 102 and the downstream side portion 110. Accordingly, the first chain unit 72 is in a state in which the first connection connecting portion 76 is linear (that is, the longest in the transfer direction) as shown in FIG. Moved.

  Further, the outer inclined portion 104 of the pitch reducing member 100 acts more greatly on the driven roller 96 of the first connection connecting portion 76 toward the downstream side in the transfer direction, and accordingly, the first and second chain links 80, When the first and second chain links 80 and 85 are turned, the length of the first connection connecting portion 76 (that is, the first chain unit 72) in the transfer direction is reduced. Then, the closer to the second transfer area 12, the more the length in the transfer direction is greatly reduced.

  Further, the intermediate portion 106 of the pitch reducing member 100 greatly acts on the driven roller 96 of the first connection connecting portion 76, and the first and second chain links 80 and 85 are up to 90 degrees as shown in FIG. Accordingly, the first and second chain links 80 and 85 are largely swung outward, so that the length of the first connection connecting portion 76 (that is, the first chain unit 72) in the transfer direction is the smallest. The first chain unit 72 moves in a state where the length in the transfer direction is reduced by half.

  Furthermore, the inner inclined portion 108 of the pitch reducing member 100 releases the action state of the first connection connecting portion 76 to the driven roller 96 as it goes to the downstream side in the movement direction indicated by the arrow 112. The first and second chain links 80 and 85 are turned so as to return to the inside, and the first and second chain links 80 and 85 are turned so that the first connection connecting portion 76 (that is, the first chain unit 72). The length in the transfer direction is restored to the original, and the reduced state is canceled so that the length in the transfer direction returns to the original length as the downstream side portion 110 is approached.

  In this embodiment, since the first and second chain links 80 and 85 of the first connection connecting portion 76 are turned to 90 degrees, the length of the first chain unit 72 in the transfer direction is reduced to half. However, by adjusting the turning angle of the first and second chain links 80 and 85 (in other words, adjusting the position of the pitch reducing member 100 acting on the dependent roller 96 of the first connection connecting portion 76), The length in the transfer direction of one chain unit 72 (so-called reduction ratio) can be adjusted steplessly.

  In this embodiment, the pitch reducing member 100 is disposed inside the first transfer chain mechanism 14, and the first and second chain links 80 and 85 are turned and reduced by the pitch reducing member 100. Contrary to this, on the contrary, the first and second chain links 80 and 85 may be pivoted inwardly by the pitch reducing member 100, and in this case, the pitch reducing member 100 may be reduced. Is disposed outside the first transfer chain mechanism 14.

  A first guide support rail 148 (the first guide support rail is omitted in FIG. 9) is disposed along the movement path along which the first transfer chain mechanism 14 moves (see also FIG. 6). ), The first clip connecting portion 74 of each first chain unit 72 of the first transfer chain mechanism 14 is guided and moved by the first guide support rail 148. More specifically, the first support roller 146 in each first clip connecting portion 74 is placed and supported on the upper surface of the first guide support rail 148, and the pair of first inner guide rollers 142 is connected to the first guide support rail 148. The first outer guide roller 134 acts on the upper surface of the inner surface, and acts on the lower portion of the outer surface of the first guide support rail 148.

This driven portion is composed of an upper driven roller 150 provided at an inner projecting end portion 144 that extends inward (rightward in FIG. 10) from the upper end wall portion 138.

  In the decelerating transfer area 10, the first clip connecting portion 74 of each first chain unit 72 of the first transfer chain mechanism 14 is moved by the drive rotating shaft 42 (which constitutes a part of the decelerating driving means). That is, the upper driven roller 150 of each first clip connecting portion 74 is moved through the movement path of the spiral protrusion 44 of the drive rotating shaft 42, and when the upper driven roller 150 moves to the deceleration transfer area 10, a predetermined direction is obtained. The spiral protrusion 44 of the drive rotating shaft 42 rotating in the direction of the first clip connecting portion 74 acts on the upper driven roller 150 (driven portion) of the first clip connecting portion 74 and moves in the transfer direction indicated by the arrow 6. The first clip connecting portion 74 is transferred integrally. At this time, since the interval between the spiral protrusions 44 of the drive rotating shaft 42 is gradually reduced toward the downstream side in the transfer direction, the first clip connecting portion 74 (that is, the first chain) approaches the second transfer area 12. The transfer speed of the unit 72) is gradually reduced, and the pitch reducing member 100 is rotated so that the first and second chain links 80 and 85 of the first connection connecting portion 76 are turned outwardly as described above in accordance with the decrease of the transfer speed.
