PURPOSE:To obtain the strip temp. distribution and shape uniform in the transverse direction of a strip by pressing the rear side of the metallic strip which contacts with cooling rolls by small-diameter press rolls at proper times in a cooling zone. CONSTITUTION:The cooling rolls No.1-No.5 are provided in the cooling zone. The strip S is threaded therebetween in such a manner that the surfaces thereof contact alternately with the rolls. The strip is thereby cooled to a desired temp. The small-diameter press rolls 1A, 1B are disposed on the rear side of the strip S in the position of the No.1 cooling roll. The rolls 1A, 1B are pressed to the roll No.1 side to bring the entire part in the transverse direction of the strip S into tight contact with the roll No.1. The rolls 1A, 1B are supported pivotally by the top end of holding rolls 2 in such a manner that the axes thereof are paralleled with the axis of the roll No.1. These rolls are formed of metallic rolls. The strip S is thereby brought into uniform contact with the roll No.1.
