PURPOSE: To completely separate slip sheets and thin plates and suck and convey them one by one by a cheap apparatus.

CONSTITUTION: Slip sheets 2 are inserted between thin glass plates 1, and have folds 3 along lines connecting points that are optionally set on the opposite sides. With the slip sheet 2 pressed by a sucking collet when the slip sheet 2 is sucked and carried by the sucking collet, a gap is formed between the middle parts of the slip sheets 2 and the thin glass plates 1, that prevents the sucking collet from sucking the slip sheet 2 and the thin glass plate 3 together at the same time. Therefore, it is not required to regulate the height of the sucking collet, and the slip sheets 2 and the thin glass plates 1 can be completely separated from each other, and sucked and carried one by one by a cheap apparatus.
