PURPOSE: To prevent the occurrence of defects in shape such as ear (vertical creases in the direction of a line) by cooling the central part of a strip in the lateral direction immediately before contact with each cooling roll.
CONSTITUTION: Each nozzle 10 for cooling the central part of a metallic strip X in the lateral direction is placed at a position just before a point at which the strip X begins to contact with a cooling roll 1. A gas or a liq. such as water or liq. nitrogen is spouted from the nozzle 10 to cool the central part of the strip X in the lateral direction. By the cooling the stress in the central part in the direction of the line is made higher than the stress in both edges. The strip X is then passed by the roll 1. By this method the occurrence of defects in shape such as ear is prevented.
