Air is sucked into the negative pressure chambers 8. At this time, since the ejection nozzles 5 and 5 and the dust suction ports 3, 3, 4 and 4 are located symmetrically with respect to the long sheet 1, the air pressure between the heads 2 and 2 and the front and back surfaces of the sheet 1 is Are equivalent, and the sheet body 1 is located in a state of being floated at an intermediate portion between the heads 2, 2, and the sheet body 1 does not contact the dust removal heads 2, 2. Therefore, the ejection of the ultrasonic air E, E from the ejection nozzles 5, 5 and the suction of the air from the dust suction ports 3, 3, 4, 4 are stabilized. Further, since the ejection nozzle 5 is inclined to the downstream side with respect to the long sheet body 1 when viewed from the side, the sheet body 1 can be fed to the downstream side.

きる。In general, when air flows at high speed over the surface of an object, a boundary layer is formed. According to this dust removing apparatus, the ultrasonic air E, E hits the front and back surfaces of the long sheet 1, so that the boundary layer is formed. It is destroyed by the ultrasonic waves, and the high-speed air directly hits the front and back surfaces of the sheet member 1, and the dust R is separated from the surface of the sheet member 1 by the effect of a so-called air knife. The separated dust R is carried by the air flow from the dust suction ports 3, 3, 4, and 4 into the negative pressure chambers 8, and further passes through an air suction path (not shown) to collect dust such as a filter. It is stored in. Thereby, dust R can be reliably removed from both front and back surfaces of the long sheet body 1.

端キャップ部11，11にて塞いでも良い場合がある。By arranging a pair of the dust removing heads 2 on both sides of the long sheet 1, a long roller can be used without contact with the long sheet 1 and a motor for driving the long sheet 1. The gap between the sheet member 1 and the dust removal head 2 can be kept constant, and the dust R can be removed from both the front and back surfaces of the long sheet member 1 at the same time. Therefore, the number of parts is reduced and the structure is simplified. And it can be easily installed even in a narrow installation space. Also,
It can be easily added to existing lines such as printing machines and winding machines. Therefore, for example, if the plate roll is added to a gravure printing machine, dust can be prevented from adhering to the plate roll via the paper (long sheet body 1), and the life of the plate roll can be extended. Also, in FIGS. 1 to 3, both ends of the two negative pressure chambers 8, 8 of the dust removal head 2 and the positive pressure chamber 9 therebetween may be closed by caps 11, 11 at both ends. .
