Abstract
PURPOSE: To measure the flatness of metal strip with a high accuracy while being rolled by correcting the tension distribution signal by the temperature distribution signal.
CONSTITUTION: A tension detecting head 1 which is adapted to be reciprocatively scanned along the width of metal strip with a drive mechanism and a tension detector 3 comprising an electronic circuit 2 are directly connected to a subtractor 7, while a position detector 4 for detecting the widthwise position of the metal strip and a temperature distribution measuring device 5 for the metal strip are connected thereto through a correction signal generating circuit 7. In this manner, the widthwise tension distribution of the metal strip is detected while it is being rolled. From the detection signal, removed are the components of the signal corresponding to the tension distribution caused by the widthwise temperature distribution of the metal strip and thus, the signal corresponding to the real flatness of the metal strip is drawn.
