What is claimed is: 1. An apparatus for making pellets of wood meal compound comprising: a twin screw type kneading and extruding machine, including a hopper in a most upstream position; a degassing cylinder disposed in a downstream direction from said hopper; a kneading section disposed in a downstream direction from said degassing cylinder; an open vent disposed in a downstream direction from said kneading section; a vacuum drawing vent disposed in a downstream direction from said open vent; an adapter disposed in a downstream direction from said vacuum drawing vent; a breaker plate disposed in a downstream direction from said adapter; a die holder disposed in a downstream direction from said breaker plate; a cutting device disposed in a downstream direction from said die holder; and a twin screw having a continuous helical thread; wherein said hopper is configured so as to simultaneously supply a combination of a synthetic resin material and a wood meal material directly to an upstream side of the degassing cylinder; and wherein the twin screw penetrates through said adapter and said breaker plate and said continuous helical thread penetrates through said adapter and said breaker plate, wherein a distal end of said twin screw passes through said die holder into said die. 2. The apparatus according to claim 1, wherein said die includes a nozzle hole fitted to a tip end of the die holder. 3. The apparatus according to claim 2, wherein a distal end portion of the twin screw passes through the die holder to be guided into a recess that communicates with the nozzle hole of the die, and wherein the recess communicates with a tapered recess of the die holder such that material fed through the breaker plate is fed to the nozzle hole through these recesses under condition that least residence occurs.
