In the above structure, when the belt 2 travels in the direction of the arrow, the water absorbing roller 9 is in contact with the back side of the belt 2 by the pressurizing spring 11 at an arbitrary pressure, so that the water absorbing roller 9 is the timepiece shown in FIG. The rubber roller 10 which is rotated in the direction and is in pressure contact with the water absorbing roller 9 is also rotated counterclockwise by the rotational force of the water absorbing roller 9. Therefore, the water ejected from the water outlet 3 is
Although guided into the water draining device 6 by being guided by the belt 2 traveling at high speed, this water is absorbed by the water absorbing roller 9 and does not flow out of the water draining device. The water absorbed by the water absorbing roller 9 is squeezed out by the rubber roller 10 and led out to the drain port (not shown) from the lower portion of the water draining device 6. In the embodiment shown in FIG. 1, the case where the water recovery groove is omitted has been described, but the invention may be applied to the case where the water recovery groove is provided.
The same effect can be obtained by using oil instead of water.

H. Effect of the Invention As described above, the present invention does not require a separate drive source because the water-absorbing roller and the rubber roller rotate due to the running force of the belt. It is sufficient if the water absorbing roller is provided, and the water absorbing roller is rotated by the running of the belt. Therefore, the difference in relative speed is small, so that the water absorbing roller is less worn. Further, there is an effect that it is not necessary to separately provide a gas pressure supply source for sealing.
