において円周値差△Ｃが検出される。 As shown in Figure 3, the external pulse transmitter signal train and the timing of opening and closing of the measurement gate are not synchronized, so the circumference value measurement data is
This may include an error equivalent to the pulse increment shown in . Therefore, when △C is calculated using equation (1), the error ratio to △C can be said to be extremely large.The purpose of the present invention is to suppress this error (E rr ) to an extremely small value that can be ignored. This is the gist. Specifically, as shown in Fig. 4, data for multiple K rotations of the rewinding machine is collected at once, the data is updated every K rotations, and the circumference value group data deviation is calculated in (8) using equation (5). , (7) gives (9)

材長Ｌが求められる。 Therefore, to express it strictly: 〓△C′=〓△C+E rr ...(6) (Circumference value difference) △C=〓△C/Y+E rr /Y ......(7) However, E rr : 1 measurement data Error included in Y: △C included in the difference between C N and C a
number (usually around 1000). Focusing on the right side of equation (7), it can be seen that the larger the value of Y, the more negligible the value of E rr becomes.
By calculating △C using this method,
Its accuracy improves dramatically. By this △C and the current circumference value C a obtained from Fig. 2 10, 1

The results of 13 and 11 are compared in 15, and if the condition of equation (4) is satisfied, deceleration starts.
