Sometimes. In this case, if necessary, as shown in the flowchart of FIG. 8, the operation of reconfirming the origin may be performed every predetermined number of rotations or every predetermined time. Specifically, each of the motors (46) and (48) is set to a predetermined speed command R1: R2 in advance.
(Step 6), and when the first kneading shaft (20) reaches the origin first (Step 7), the output of the first motor (46) is reduced and the second motor (48) is turned off. The output is increased and adjusted so that the kneading shafts (20) and (22) are synchronized (step 8). Conversely, when the second massaging shaft (22) reaches the origin first (step 9), the output of the second motor (48) is reduced and the output of the first motor (46) is increased. Then, the massaging axes (20) and (22) may be adjusted so as to be synchronized (step 10).
