PURPOSE:To mix a plurality of stock materials under the condition that the mixing ratio is varied by a single mixing head and, at the same time, without increasing the numbers of nozzle structure and of stock material metering and supplying system by a method wherein the degree of opening of a discharge port is controlled by an opening and closing body by controlling the moving position of the opening and closing body toward its opening direction through the positional controlling of a controlling body in the structure concerned. CONSTITUTION:A nozzle structure 61 controls the delivery of stock liquid I by controlling the degree of opening of a discharge port 63 with an opening and closing body 68 through the controlling of its moving position toward its opening direction by controlling the position of a controlling body 75. In addition, a mixing head 21 is to mix stock liquids P and I by collision in a mixing chamber 23 by discharging the stock liquids P and I from nozzle structures 50 and 61, which are opposite to each other, in the mixing chamber 23. By controlling the delivery of the stock liquid I with the nozzle structure 61, the mixing ratio between the stock liquids P and I is changed. |
