portion of the spindle 3 toward the upper portion of the spindle so that the deodorizing solution is uniformly discharged and the spray pressure of the deodorizing solution is increased namely the deodorizing solution introduced into the spindle 3 is discharged from the spindle 3 through the through holes 32 in which the deodorizing solution is smoothly discharged at the lower portion of the spindle due to high pressure whereas the deodorizing solution is not smoothly discharged at the upper portion of the spindle because the pressure decreases toward the upper end thus the amount of deodorizing solution supplied is different between the bobbins u201c b u201d located at the upper and lower portions of the spindle 3 so that the deodorizing performance is different between the upper and lower portions of the spindle 3 to overcome this problem according to the present invention the guide vane 33 that guides the deodorizing solution introduced into the lower end of the spindle 3 to the upper portion of the spindle 3 is formed so that the bobbins u201c b u201d located at the upper and lower portions of the spindles 3 can be uniformly treated with the deodorizing solution also because the deodorizing solution that is sprayed through the through holes 32 is discharged from the spindle 3 while it is rotated by the guide vane 33 in the.
