Abstract: In continuous rolling of a plurality of steel strips: 1. a table speed corrector corrects speeds of tables, on which a succeeding steel strip is placed, through a main controller so that values of an interval between steel strips, obtained by CCD cameras before the preceding steel strip is rolled, are set to a first set value preset as an interval so the preceding and succeeding steel strips do not come into collision with each other due to a reduction in speed when the preceding steel strip is caught; 2. the table speed corrector corrects speeds of the tables, on which the succeeding steel strip is placed, through the main controller so that values of an interval between steel strips, obtained by CCD cameras when the preceding steel strip is being rolled, are set to a second value preset as an interval at which the succeeding steel strip is caught by the rolling mill 1 at the same time at which the trailing end of the preceding steel strip has passed therethrough; and 3.
