PCT No. PCT/JP97/00467 Sec. 371 Date May 29, 1998 Sec. 102(e) Date May 29, 1998 PCT Filed Feb. 20, 1997 PCT Pub. No. WO97/33709 PCT Pub. Date Sep. 18, 1997Synchronization of the drive bars of a servo transfer system is safely restored, while avoiding mechanical damage as much as possible. A synchronization position C for all the drive bars is determined from the respective present positions B of the drive bars and the respective deviations of the present positions B from the synchronization position C are determined. Then, servo motors for all the drive bars are so controlled that the drive bars move the distances corresponding to their respective deviations within the same period of time.
