Abstract
In a floating type web conveying device, an air jetting box comprises an air jetting surface in which lines of air jetting holes are formed in such a manner that the lines are extended in the widthwise direction of the web and the sum of the areas of the air jetting holes range from 1% to 3% of the area of the air jetting surface, so that the web is substantially free from the difficulty that it is brought into the contact with the air jetting box.
