PURPOSE:To prevent an organic solvent from being released into the atmosphere and to remove the oil content, etc. attached to a sheet by cleaning the expanded sheet through a scouring tank containing two layers of the organic solvent and water then by filling a paste-like material. CONSTITUTION:Trichloroethylene as an organic solvent 5 and water 9 are put in a scouring tank 6. At this time, the density of the trichloroethylene is much higher than that of the water 9 and is hardly dissolved in the water 9, therefore, the layer of the trichloroethylene 5 is formed below and the layer of the water 9 is formed above completely in two layers. Next, a sheet 3 attached with the oil content is first guided through the trichloroethylene as the organic solvent 5 below to remove the oil, and subsequently it is guided through the water 9 above to substitute the trichloroethylene attached on the surface with the water 9. Then, it is guided through a drier 7 to remove the attached moisture, and finally the active material is filled to it by a filling machine 4. |
