Abstract
PURPOSE: To enhance the accuracy of the distance between the adjacent runner blades to improve the efficiency of wind flow, by arranging, on a flat runner blade material, those U-shaped drawn parts longer than the interval of the array, by a certain length, cutting off the one end of each drawn part to arrange it in the regular form of blade, and finally forming the blade material in a circle.
CONSTITUTION: U-shped drawn parts 7 are attached of a flat runner blade material 6 at an equal distance P. The length D of a drawn part 7 is selected to be about 1.3 miles the distance P. Then, the one end of each drawn part 7 is cut off, subsequently arranged in a form of blade 8. Therefore, width D of the blade 8 is 1.3 times the distance P. Then, the flat material 6 is formed in a circle, while the central holder not shown in the figure is caulked to form a runner. In this structure, the accuracy of distance between the adjacent blades can be well enhanced to improve the efficiency of wind flow.
