Abstract

PURPOSE: To perform a marking by detecting a position in the breadth direction of the marking with the combination of detecting signal of a detector for position in the breadth direction and that of a steel sheet end portion to be subjected to a marking treatment.
CONSTITUTION: In order to detect a position in the breadth direction of a steel sheet by a position detector SO in the breadth direction of a steel sheet marking at a point of time when the rear end of a conveying steel sheet is detected by a photoelectronic switch 4 of said conveying steel sheet, the position where a photoelectronic switch 5 passes the light and a photoelectronic switch 6 shielding the light is judged to be a normal position in the breadth direction of the steel sheet. When the steel is biased to right, the stamping or blowing is stopped and an abnormal signal of the positiok in the steel sheet breadth direction is outputted to a line control computer CO. At the same time, a warning indication is performed. By using 3 couples of photoelectronic switches 6 in this way, the marking to the steel sheet can be automated.
