ABSTRACT:
A kneading and extruding apparatus for extrudable material such as soap material and its additives, comprising a perforated rotating disc at an output end of a kneading screw shaft, a perforated stationary disc adjacent to the rotating disc to form a clearance therebetween, a punching plate fixed to the stationary disc confronting the rotating disc and formed with a great number of small holes having a diameter smaller than those of the holes of the rotating and stationary discs, and a blade-like cutter for serving the material extruded through the holes of the stationary disc. The material is sheared in the clearance between the rotating disc and the punching plate to blend the material and the additives effectively.
