Abstract
Provided is a method for feeding a granular powder from a granular powder feeding hopper onto an upper surface of a sheet material. A feeding passage is disposed so as to extend downward from an outlet of the granular powder feeding hopper so that the lower end of the feeding passage faces the upper surface of the sheet material moving beneath the feeding passage. The feeding passage is opened and closed by the open-close means so that the granular powder is intermittently fed from the granular powder feeding hopper onto the sheet material.
