る。As described above in detail, according to the present invention, the liquid chamber of the submerged floater is divided into a central liquid chamber and end liquid chambers on both sides of the liquid chamber. the chamber, since each is provided separately the first and second pump and each of the liquid jet nozzle for the liquid fed, when the width of the strip material is narrow, because the liquid fed for end fluid chamber The second pump is stopped, and only the first pump for supplying liquid for the central liquid chamber is operated to supply liquid from the liquid ejecting nozzle in the central part to the strip. Even when sprayed, the strip can be brought out of sufficient contact with the submerged floater. Therefore, with a narrow band, it is only necessary to operate the first pump with a small output for the central liquid chamber, and to stop it by stopping the second pump for the end liquid chamber. Power can be reduced.
