Abstract

PURPOSE: To prevent the biting shock of the succeeding materials by calculating the spacing between the both rolling materials based on the detection of detecting means and so controlling the speed of the succeeding material so as to increase the same based on this calculated value and the conveying speed of the preceding rolling material.
CONSTITUTION: A reference point is set in front of an inlet side feed roller 4 on the conveying path of the rolling material. The time when the trailing end of the preceding material 1 passes the reference point is detected with a trailing end detector 9 and the leading end of the succeeding material 2 of that time is detected and the spacing lg from the reference point and the leading end of the rolling material 2 is measured. The speed Ve' of the rolling material 2 is obtained by measuring Ve, lg so as to make the spacing of the both rolling materials 1, 2 zero after the t second by as shown in formula I (l2; the distance from the rolling machine center up to the reference point, l1; the distance from the rolling mill center at the point where the spacing between the both materials becomes zero; Ve; speed of the preceding material 1).
