Since a steel plate as rolled is curved or has an irregular width shape, it is first necessary to know the shape of the steel plate in order to cut it economically and rationally without waste. For this reason, conventionally, the shape of a steel plate has been measured in advance using a steel plate shape measuring device as shown in FIG. This steel plate shape measuring device consists of a table roller 2 that conveys the steel plate 1, a length meter 3 that measures the amount of movement of the steel plate 1, a width meter 4 that detects the position of both side edges in the width direction of the steel plate 1, and a length meter 3. Obtained steel plate 1
A calculation device (not shown) configured to obtain the shape of the steel plate 1 from the signal of the longitudinal position of the steel plate 1 and the signal of the side edge position of the steel plate 1 in the width direction obtained by the width gauge 4.
It consists of

1, it moves in a loop between the support arms 8. Since the paint applicator 13 is in contact with the wire 10, the paint is applied to the surface of the wire 10 in a wet state. This wire 1
0, when the steel plate 1 is being conveyed and is in the state shown in FIG. and draw continuous marks 7 on the longitudinal surface of the steel plate 1. This mark 7
is drawn so that the longitudinal position of the steel plate 1 can be detected, such as ``...'' or ``''. The steel plate 1 on which the marks 7 are drawn is conveyed as it is, and as it passes under the detector 15, the division or number of marks 7 is counted as shown in FIGS. 7 and 8. At the same time, the displacement of the mark 7 in the width direction is detected. Further, the positions of both widthwise edges of the steel plate 1 are detected by the width gauge 16.

得られる。 The calculation device 17 first determines the shape of the steel plate from the signal of the longitudinal position of the steel plate obtained by the detector 15 and the signal of the position of both side edges of the steel plate in the width direction obtained by the width gauge 16. Here, the positions of both side edges in the width direction of the steel plate are determined as distances l 1 and l 2 from the reference point a, as shown in FIG.
If the steel plate 1 is skewed by y in the Y direction, the obtained steel plate shape will be a curved shape surrounded by line A and line B in FIG. Therefore, the calculation device 17 further corrects the above-mentioned shape by -y using the signal of the amount of skew of the steel plate 1 detected by the detector 15. That is, by aligning the mark 7 with the wire center line C, lines A and B are corrected by the same amount in the Y direction. As a result, the correct shape of the steel plate 1 surrounded by lines A and B in FIG. 11 is obtained.

よつて鋼板１の正しい形状が求められる。 In short, "marks 7 separated by a certain distance" are drawn on the steel plate 1 with the marker 6 in the steel plate transport direction, the position of the mark 7 is determined with the wire center line C as a reference using the detector 15, and the width is measured. 16, find the trajectories A and B of the distances l 1 and l 2 from the reference point a to the positions of both side edges of the steel plate for each break point of the mark 7,
If we move parallel to the Y axis from these trajectories A and B by the amount of skew (distance y from wire center line C to mark 7) and find trajectories A' and B', we can use these trajectories A' and B'. Therefore, the correct shape of the steel plate 1 is required.
