PURPOSE: To form a reinforcing material-containing panel for building material having high bending strength and impact resisting force.
CONSTITUTION: An extrusion molding machine 1 for building material consists of a conveying section 2 for supplying a kneaded material and an extruder body having a deaerating chamber 4 and an extruding section 5. In the extruder body, a press-fitting tube 6 which fits with pressure the kneaded material uniformly, gives fluidity of a laminar flow, and pulls out a reinforcing material 7 to be inserted by surrounding and squeezing it is mounted. Lastly, a mouthpiece 9 for deciding a shape of a product of an extrusion molded body 15 is mounted in the tip of the press-fitting tube 6. A leading tube 8 is provided for inserting the reinforcing material 7 and is arranged in a leading passage of the reinforcing material 7 by penetrating from the outer wall of the press- fitting tube 6. The diameter of the leading tube 8 has an aperture similar to the outer diameter of the reinforcing material 7.
