PURPOSE:When a bundle of laver sheets are folded with a folding arm, the folder is assembled so that the center of the laver bundle is held by the bending arm and the support roller set in the lower position to ensure folding on the center line. CONSTITUTION:When the laver sheet bundle goes in the direction of the arrow A, the top end of the bundle 10 comes into contact with both the left stopper 14A and the right stopper 14B. At this time, the rotation of the belt 12 is stopped. The truing bar 21 is swung several times in the arrow G direction to come into light contact with the back end of the laver sheet bundle. Thus, the laver sheet bundle is arranged in a flat surface in the lengthwise direction. Then, cam 19 is rotated in the arrow H direction. The folding arm 15 comes down so that the laver bundle 10 is held on its center by the contact part 15B and the supporting roller 20A and they go down. The bundle 10 is folded into 2 pieces at the center line. |
