PROBLEM TO BE SOLVED: To provide a rewinder sizing controller eliminating a tension fluctuating factor and reducing an acceleration time for improvement operation efficiency. SOLUTION: According to a load factor B from a drum load detector 24, an acceleration upper limit value computing circuit 25a decides a maximum accelerationαam, and using this maximum accelerationαam, a speed reference computing circuit 18 computes a speed reference. An achievable speed computing circuit 26 performs approximation to a winding speed set value by using the maximum accelerationαam and computes an achievable speed Vs for fixing the speed reference without correcting the acceleration so as to give it to the speed reference computing circuit 18. A sizing movement eliminating speed computing circuit 27 computes a movement eliminating speed vo for sizing control when a deceleration start is detected so as to give it to the speed reference computing circuit 18. In this way, a tension fluctuating factor can be eliminated.
