  • the second holding portion 24 when the second holding portion 24 holds the lower portion 21b at the end portion in the width direction of the sheet material 21, it is held including the lower end portion 21c at the end portion in the width direction, but is not limited thereto.
  • the second holding portion 24 may not hold the lower end portion 21c of the width direction end portion, in other words, a portion immediately above the lower end portion 21c. May hold only.
  • the second holding unit 24 may appropriately hold part or all of the end portions in the width direction of the region where the distance ratio D1 / L1 is 0 to 0.4.
  • D1 is the distance (mm) from the lower end 21c of the sheet material
  • L1 is the length (mm) of the sheet material 21 (see FIG. 8).
  • the first holding portion 23 holds the upper portion 21a at the end portion in the width direction of the sheet material 21, the first holding portion 23 holds the upper end portion of the end portion in the width direction, but is not limited thereto.
  • the first holding portion 23 may not hold the upper end portion of the width direction end portion.
  • the holding of the first holding part 23 may be appropriately performed so that the portion of the sheet material 21 located above the first holding part 23 does not hang down due to its own weight (so as not to be bent).
  • the second holding portion 24 of the above embodiment can be moved toward and away from the pallet 7 by the first guide member 25 and can be moved up and down by the second guide member 26, but is not limited thereto.
  • the second holding unit 24 may be configured not to move up and down, and may be allowed to approach and separate only from the pallet 7 by the first guide member 25.
  • the vertical position of the second holding portion 24 is the same position as the lower portion 21b of the sheet material 21 at the installation position.
  • a third holding portion is arranged, and the third holding portion cannot approach / separate only with respect to the pallet 7 and can only move up and down by the second guide member 26.
  • the sheet material 21 is transported to the position immediately before the pallet 7. Meanwhile, in the embodiment using the third holding member, the third holding member is used instead of the second holding unit 24. At the position immediately before the pallet 7, the lower part 21 b of the sheet material 21 is transferred from the third holding member to the second holding unit 24. After delivering the lower part 21 b of the sheet material 21, the third holding member cuts out the next sheet material 21. In the embodiment using such a third holding member, the cutting of the next sheet material 21 is started before the sheet material 21 is moved to the installation position, so that the tact time can be shortened.
