Method and apparatus for producing ceramic green sheet

A method for producing ceramic green sheets by applying ceramic slurry on a long carrier film, said method comprising the steps of:

• transferring the carrier film in the longitudinal direction thereof and in contact with a support roll;
• removing foreign substances on the carrier film by using a cleaning roll, wherein the cleaning roll is disposed in an area of a wrapping angle defined by the area in which the carrier film makes contact with the support roll, the wrapping angle of the carrier film in contact with the support roll is not less than about 90°, the carrier film is sandwiched between the support roll and the cleaning roll, the cleaning roll contacts the carrier film surface that is opposite to the carrier film surface that is in contact with the support roll, and the cleaning roll is arranged to contact the carrier film at a portion of the carrier film that is in contact with the outer peripheral surface of the support roll;
• and
• forming a ceramic green sheet by applying ceramic slurry on at least one surface of the carrier film after said foreign substances have been removed.
