PROBLEM TO BE SOLVED: To control the bank amount of rubber between rolls precisely by detecting the cut-out side edge of a rubber sheet which was kneaded while being wound onto one roll of a roll kneader and regulating the amount of rubber supplied between the rolls by the quantity of deviation between its edge position and a standard position. SOLUTION: The cut-out side edge E of a rubber sheet R1 which was kneaded while being wound onto one roll 10a is detected by an edge detecting means 13. The signal is received, and the quantity of deviation between its edge position and a standard position set up corresponding to the proper amount of rubber R which was kneaded in advance is obtained by a control means 20. Based on the deviation, the amount of rubber supplied between rolls 10a, 10b is regulated to control the bank amount. Even when the shapes of supplied rubber blocks on the bank between the rolls 10a, 10b are various and complex, since a proper bank amount can be measured irrespective of the shapes, the bank amount can be controlled precisely. |
