  FIG. 7A is a cross-sectional view at a first position that is a starting position where the locking portion 41 is folded back by the folding belt member 121. FIG. 7D is a cross-sectional view at a fourth position, which is an end position where the locking portion is folded back by the folding belt member. FIG. 7B is a cross-sectional view at a second position downstream of the first position in the transport direction. FIG. 7C is a cross-sectional view at a third position downstream of the second position in the transport direction and upstream of the fourth position in the transport direction.

  A region in contact with the folding belt member in the locking portion 41 and a region on the inner side in the crossing direction from this region become a folding base portion 41 </ b> A that is folded by the folding belt member 121. Moreover, the area | region inside the cross direction rather than the folding origin part 41A of the latching | locking part 41 becomes the folding part 41B where a folding origin part is piled up. In the present embodiment, the folding base portion is provided on the surface of the locking portion 41 on the conveyance mechanism side (the upper surface shown in FIG. 3), and the folding end portion 41B is on the folding mechanism side of the locking portion. It is provided on the surface (the lower surface shown in FIG. 3). The folding part 41 </ b> A of the locking part 41 is folded as the angle of the folding belt member 121 with respect to the web 7 changes. In the first position, the folding belt member 121 is disposed on the outer side in the intersecting direction than the imaginary fold line (shown as FL to coincide with the fold), and above the locking portion 41, which becomes the fold FL for folding the locking portion 41. Has been. The folding belt member 121 is twisted so as to rotate in the clockwise direction shown in FIG. 6 about the folding imaginary line FL from the first position toward the second position.

  Accordingly, the bottom surface 121A of the folding belt member 121 that contacts the web is substantially parallel to the transport belt member 111 at the first position, but is substantially perpendicular to the transport belt member at the second position. In the second position, the angle formed by the fold portion 41A and the fold portion 41B of the locking portion 41 is approximately 90 degrees.

  In the second position, the folding belt member 121 is disposed below the folding imaginary line FL. The folding belt member moves from the second position toward the third position in the clockwise direction shown in FIG. 6 about the folding imaginary line. In the third position, the folding belt member is arranged below the folding imaginary line. The fold base portion 41 </ b> A of the locking portion is disposed below the web 7.

  The folding belt member 121 moves in the clockwise direction around the imaginary folding line from the third position toward the fourth position. In the fourth position, the folding belt member 121 is disposed on the inner side in the intersecting direction with respect to the folding imaginary line FL and below the folding imaginary line FL. The bottom surface 121 </ b> A of the folding belt member 121 is in a state of facing the outer peripheral surface 111 </ b> A of the conveyance belt member 111. The folding part 41A of the locking part 41 overlaps the folding part 41B.

  In the present embodiment, the state in which the fold portion 41A overlaps the fold portion 41B is not limited to the configuration in which the fold portion is directly overlapped with the fold portion, for example, the fold portion 41A. Includes a configuration in which a web or the like is disposed between the fold-end portion 41B and the webs are overlapped via the web.

  As described above, the locking portion 41 can be folded back based on the fold line on the locking portion along the folding belt member 121. Since the locking part 41 can be folded along the contact position between the folding belt member 121 and the locking part 41, the engagement point 41 has a fold on the locking part 41 having a relatively higher rigidity than the web. The stop 41 can be folded back. In addition, the folding belt member 121 is configured to move in the rotational direction about a fold imaginary line FL serving as a fold. Therefore, it is possible to prevent the misalignment of the fold line as compared with the configuration in which the folding belt member is displaced along the intersecting direction.

    The suction hole is disposed on the inner side in the crossing direction than the fold line FL. With the suction member, only the fold portion 41B can be adsorbed without adsorbing the fold portion 41A arranged on the outer side in the width direction than the fold. By adsorbing the fold base portion, it is possible to prevent the displacement of the fold base portion when the locking portion is folded back, and to prevent the position shift of the fold.

  The rotation center of the folding belt member overlaps the imaginary line of folding, and is intermediate between the folding belt member at the first position, which is the folding start position, and the folding belt member at the fourth position, which is the folding end position. Position. That is, the position of the folding belt member at the first position and the position between the folding belt members at the fourth position (the position between the crossing directions and the position between the vertical directions) is the center of rotation. Therefore, by appropriately moving the first position and the fourth position, it is possible to adjust the position of the folding imaginary line that becomes the fold.

  Specifically, the position of the folding belt member 121 at the fourth position can be changed by moving the second roller 122B in the crossing direction and the vertical direction, and the first roller 122A and the second roller 122B can be moved in the crossing direction. And a 1st position can be changed by moving to an up-down direction.
