PURPOSE:To prevent a bridging phenomenon at an auxiliary raw material loading port, by a method wherein auxiliary raw materials are fed to the titled machine while gas to be generated from molten main raw material resin is being deaerated through a deaeration port provided close by the auxiliary raw material loading port. CONSTITUTION:Resin is loaded through a main raw material loading port 3, the molten resin is mixed with a glass fiber by loading the glass fiber through an auxiliary raw material loading port 4 and gas such as moisture generated through said molten resin and air streamed in through the auxiliary raw material loading port are deaerated through a deaeration port 9 provided close by the auxiliary raw material loading port, in an extrusion machine having a feed screw or rotor 2 within a cylinder 1 and having the main and auxiliary raw material loading ports 3, 4. As auxiliary raw materials are loaded while deaeration is being performed, it does not happen that a bridging phenomenon is generated through adhesion of the moisture generated from the molten resin to the glass fiber. |
