Of the fold forming roller 62, a soft member 76 for forming the fold 28 on the interleaf 14 between the teeth 72, 72,. It is attached in the circumferential direction. In other words, the crease 28 is satisfactorily formed on the interleaf paper 14 by the predetermined amount of the rotated teeth 72 biting into the soft member 76.

  As a result of the rotation of both the crease forming roller 62 and the backup roller 74, folds 28, 28... Are formed at predetermined intervals on one side of the slip sheet 14 (50) fed by the feed rollers 54, 54. The Then, the interleaf 14 on which the folds 28 and 28 are formed slides along the guide member 64 shown in FIG. 6 and is guided toward the glass plate 12. When the slip sheet 14 is placed on the glass plate 12, one side portion of the slip sheet 14 in which the folds 28, 28... Are formed is positioned outside the one side portion of the glass plate 12.

  When the glass plate 12 on which the slip sheet 14 is placed is loaded on the pallet 10 in FIG. 1, the folds 28, 28... Formed on the slip sheet 14 are placed on the pallet 10 so that the upper side portion is formed. To load. By stacking in this way, the slip sheet 14 can be reliably sucked by the slip sheet suction pad 30 when the glass plate 12 is taken out from the pallet 10.

  The rotational speeds of the crease forming roller 62 and the backup roller 74 are set in accordance with the rotational speeds of the feed rollers 54, 54. Therefore, the interleaf 14 on which the creases 28, 28. Is smoothly placed on the glass plate 12 being conveyed.

  The crease forming roller 62 is provided with teeth 72 for forming the crease 28 in the interleaf 14. However, as described above, when forming irregularities on one side of the interleaf 14, a crease is formed.
