However, there is a drawback that the plate-like material itself is lifted up by the blow when it is conveyed by a belt, a roller, or the like, and is sucked up by vacuum. A method is employed in which a plate-shaped material is sucked by a vacuum suction table (hereinafter, simply referred to as a table) and the table is run.
Therefore, dust adhering to the lower surface of the plate-shaped material (the surface adsorbed on the table) could not be removed.

In addition, the conventional method has a drawback that dust blown up by blowing cannot be completely sucked off by vacuum and reattach to the plate-like material. That is, a part of the blown air is blown to the table carrying tool (ball screw or the like), so that the dust generated here and the dust that cannot be completely sucked up are sowed up and reattached to the plate-shaped material. To avoid this, the size is about three times the size of the plate
And the tables, must have a structure to block the outlet bottom in the table, there was a drawback that the apparatus becomes large.

When suction is performed from the lower portion of the box 3 by a blower device or the like, a negative pressure is generated in the box, and a large amount of air flows from the gap a between the intermediate roller 5 and the adhesive roller 6 and the gap b between the rollers and the box. It flows into the body. When the glass plate 2 is conveyed in this state, the portion 8 surrounded by the intermediate roller 5 and the adhesive roller 6 becomes a negative pressure against the outside air, and the force of pressing the glass plate 2 against the adhesive roller 6 is reduced. Works.
