Document Type and Number:
Japanese Patent JP7031247
Kind Code:
B2
Abstract:
To provide a method and an apparatus for kneading a rubber material, in which a powdery compounding agent can be dispersed more evenly in raw material rubber without being excessively compressed, by using a hermetically sealed type kneading machine.SOLUTION: A method for kneading a rubber material includes the steps of: inputting phase data according to rotation of one set of rotors 3 into a control part 12; successively calculating an area S of a gap 5c between the set of rotors 3 in a top surface view, on the basis of the phase data using the control part 12; and kneading a kneading object R containing a raw material rubber G and a powdery compounding agent N inputted to a kneading chamber 5 by using the rotating set of rotors 3, while the control part 12 adjusts a vertical direction position of a ram 6 detected by a position sensor 14, on the basis of size of the area S of the successively calculated gap 5c.SELECTED DRAWING: Figure 3
