Title:
METHOD AND DEVICE FOR ALIGNING WIDTHS OF PRECEDING AND FOLLOWING METAL PLATES AND CONTINUOUS ROLLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/135802
Kind Code:
A1
Abstract:
A method and a device for aligning the widths of preceding and following metal plates in which a curve can be corrected in the vicinity of a joint by reducing width mismatching at the bonding position of the preceding and following metal plates as much as possible. For that purpose, a device (3) for bonding the trailing edge of a preceding sheet bar (9) and the leading edge of a following sheet bar (6) when they are traveling in the pass line direction, first and second curve measuring instruments (20, 21) for detecting curved states at the trailing edge of a preceding sheet bar and the leading edge of a following sheet bar prior to bonding, fourth and fifth longitudinal pair rollers (25, 26) for shifting at least one of the preceding sheet bar and the following sheet bar in the width direction at the bonding position, and a controller (30) performing drive control of the fourth and fifth longitudinal pair rollers to reduce the deviation in the center position in the width direction between the trailing edge of a preceding sheet bar and the leading edge of a following sheet bar at the bonding position based on the detection signals from the first and second curve measuring instruments are provided.
