PURPOSE: To make possible profiling operation using automatic operation data without carrying out manual editing and input operation, by taking-in processing condition data required at the time of actual operation, editing and storing these as automatic operation data, and outputting a control command based on these data at the time of automatic operation.

CONSTITUTION: When a data taking button 15 is pressed at every step, the data at the time are automatically collected and memorized in a memory 22 via an interface 23. By pressing a data editing button 18, the collected data are classified according to the type of the elastomer and the ambient temperature, and are stored as copying operation data for preregistered respective type numbers into the corresponding memory areas. Then when a type number in a key board 12 is hit, the data suitable for the kneading sequence and the ambient temperature at the time are displayed in a monitoring television 13, and further when a start button 16 is pressed, a copying operation is effected according to the data automatically.
