CONTINUOUS WASHING METHOD AND CONTINUOUS WASHING APPARATUS FOR SHEET

摘要

PROBLEM TO BE SOLVED: To provide a continuous washing method and a continuous washing apparatus for removing dust, adhering substances, or precipitates of a sheet such as a carrier-bearing ceramic green sheet and excellent in mass productivity. SOLUTION: High pressure washing water is jetted from the carrier film side to a carrier film-bearing ceramic green sheet 20 to be fed from a supply roll 56 to a rolling roll 57 and compressed air is blown from an air knife 40 to remove water of the carrier film-bearing ceramic green sheet 20 and then the carrier film-bearing green sheet 20 is dried by removing water by a hot air blowing drier 50. In the high pressure washing water jetting process, a belt conveyer 33 for receiving the carrier film-bearing ceramic green sheet 20 while being moved at a speed same as the feeding speed of the sheet 20 is installed in the ceramic green sheet side of the carrier film-bearing ceramic green sheet 20.
