  As the material is transferred to the position of the upper surface roller brush body 104 and the material is transferred toward the outlet, the material pushes up the upper surface roller brush body 104, and the upper surface roller brush body 104 is lifted to a predetermined angle. Thereby, brushing is performed along the upper surface of the material.

[Air duct 105]
The air duct 105 blows air to the top, bottom, left, and right of the material, and includes an upper surface nozzle 105a, a lower surface nozzle 105b, a left nozzle 105c, and a right nozzle 105d. The air duct 105 communicates with a blower 107 installed below the material transfer device 101, and the air blown from each of the nozzles 105a to 105d is blown out from the blower 107.

[Filter 106]
The filter 106 filters air containing dust, sucks air from the gaps between the plurality of rotating rollers 101a of the material transfer device 101, and removes dust contained in the air.

[Blower 107]
The blower 107 supplies air to the communicating air duct 105. As the supplied air, the blower 107 sucks the air filtered by the filter 106 and supplies the sucked air to the air duct 105.

Next, the operation of the side roller brush body 103 will be described with reference to FIG.
First, as shown in FIG. 4A, the material is transferred by the material transfer device 101 in the installation direction of the side roller brush body 103. Next, as shown in FIG. 4B, when the material is transferred by the material transfer device 101 to the installation location of the side roller brush body 103, the material starts to be brushed by the rotating brush 103 </ b> B. When the material is transferred in the direction of the arrow by the material transfer device 101, the material pushes out the side roller brush body 103, and the side roller brush body 103 swings outside the material transfer device 101.

  Next, FIG.4 (c) shows a mode that the side roller brush body 103 is brushing the side surface of material. When the material is transferred to a position where the side roller brush bodies 103 are in contact with each other as shown in FIG. 4A, the side roller brush body 103 is further pushed to the outside of the material transfer device 101 in accordance with the width of the material. Can be spread. Then, as shown in FIG. 4D, when the material passes through the installation position of the side roller brush body 103, the side roller brush body 103 that has been spread to the outside of the material transfer apparatus 101 by the material is shown in FIG. Return to the position shown in

Next, the operation of the upper roller brush body 104 will be described with reference to FIG.
