<p>PURPOSE:To accurately regulate the temp. of a traveling wire body in a short period of time by compensating the deviation in the zero point in the input characteristics of a heating means and controlling a means for regulating electric energy at the point of the time when a line speed is changed. CONSTITUTION:The temp. before heating of the wire body W is measured by a temp. detecting section 33 and is inputted to a control section 13. The heating temp. of the wire body W is inputted from a setter to the control section 13. An output setting volume control 14a is regulated after the control section 13 starts operating. The control section 13 reads the voltage of the output setting volume control, output voltage, output current and line speed voltage therein and determines a reference electric power from these values. The output setting volume control 14a is regulated again to determine the true temp. before heating when the temp. before heating, etc., change. The control section 13 substitutes the previously stored voltage of the setting volume control, reference output voltage, reference output current and reference line speed voltage with the present values and determines the fresh reference electric power.</p> |
