Apparatus for mixing and degassing components of synthetic resins, particularly thermo-setting synthetic resins

In an apparatus for mixing and degassing components of synthetic resins, comprising an evacuatable, chamber means having a top wall, a cylindrical wall structure and a downwardly and inwardly tapered conical wall structure and a bottom wall structure at the lower end thereof, means defining an opening into said chamber means for facilitating an evacuation of said chamber means, a rotatable worm conveyor centrally arranged in said chamber means and closely surrounded by an elongated vertically upstanding guide tube, the ends of which are spaced from the top and bottom walls of said chamber means, securement means for fixedly securing said guide tube to said chamber means, said guide tube having at its top end a discharge plate, and including between the lower end of said guide tube and said conical wall structure of said container at least one radially extending agitating arm secured to said worm conveyor at the lower end thereof, the improvement comprising wherein at least one collecting arm is secured to and projects radially from said guide tube, said collecting arm extending above said agitating arm, is spaced a small distance from said wall structures of said chamber means, and has means defining a collecting opening which faces in a direction opposite the direction of rotation of said agitating arm, and means defining an opening connecting an interior cavity in said collecting arm to the interior of said guide tube.
