KNEADING MIXER/RUBBER SHEETING APPARATUS

摘要

PURPOSE: To provide the subject apparatus capable of preventing the generation of residual rubber and capable of certainly molding supplied kneaded rubber into a rubber sheet material having definite width and thickness. CONSTITUTION: An auxiliary pressure part 9 is provided to the leading end of a pusher 5 and has at least two side surfaces 9B, 9C crossing each other at a right angle and a press surface 9A being a curved surface and one side surface 9B is fixed to the leading end surface of the pusher 5 and the side surface 9C is arranged along the peripheral wall of a feed chamber 11 while the press surface 9A is formed so that the distance between the side end of a chute 1 and the outer periphery of a screw rotor 4 becomes smaller than that between the side end of the side surface 9C and the outer periphery of the screw rotor 4. When the pusher 5 reaches the lowermost point, only a slight gap is left between the press surface 9A and the outer periphery of the screw rotor 4.
