Document Type and Number:
Japanese Patent JP7283132
Kind Code:
B2
Abstract:
To provide a rubber extruder capable of simultaneously realizing a quality and productivity of an unvulcanized rubber of high viscosity.SOLUTION: A rubber extruder 1 includes: a barrel 2; an input part 3 for inputting unvulcanized rubber G inside the barrel 2; and a screw 5 for extruding the unvulcanized rubber G inputted inside the barrel 2 in an extrusion direction A. Inside the barrel 2, there are provided: a parting part 6 for parting the unvulcanized rubber G; a kneading part 7 for locally kneading the parted unvulcanized rubber G; and a compression part 8 for compressing the kneaded unvulcanized rubber G in the extrusion direction A. The compression part 8 is configured to taper a space volume between flights 5b of the screw 5 toward the extrusion direction A of the unvulcanized rubber G.SELECTED DRAWING: Figure 1
