<p>PROBLEM TO BE SOLVED: To enable great increase of an amount of air jetting without hindering the flow of air in a main stream by effectively using a negative pressure condition at the front of an air jetting part and enable local jetting to a jetting object position.SOLUTION: In a flat type air nozzle 1 whose entirety is flat, an air inlet part 2 is provided on a base end 1a side, an air jetting part 3 is provided on a tip 1b side, and the inside is formed in a hollow part 4 communicating with the inlet part 2 and the jetting part 3. In the front face of the jetting part 3, a plurality of air jetting holes 5 are provided in a line while being spaced at predetermined intervals in a lateral width direction. Longitudinal and lateral frames 6, 9 are formed on the front face edges of the jetting part 3, and in the bases of the lateral frames 6, intake and exhaust openings 7 for introducing air from the outside are formed while being spaced at predetermined intervals in the lateral width direction.</p> |
