Abstract

PURPOSE:To make it possible to mix a main ingredient and a liquid additive evenly, by using a single-shaft screw type extruder in which a plurality of grooves are provided through the screw groove parts in front and at the back of a flight near the liquid injection port. CONSTITUTION:A liquid additive is injected into the extruder from liquid injection port 3. It is mixed with resin fed from hopper 4. Since cut groove 9 is formed on the screw flight near the place where the liquid additive is injected, even if the liquid additive is not evenly dispersed into resin and tends to remain in the part rising toward the flight at the back from the bottom surface of the screw groove part, the liquid additive leaks into the screw groove part in the back from cut groove 9 and is mixed with resin in the screw groove part in the back, and thereby it is evenly mixed with resin. Further, eddies are produced in the screw groove part and the effect of even dispersion is accelerated.
