Roll coater control method and roll coater |
摘要 |
Prior to starting, the size of a clearance, defined on a second end side of a roll when an end of a coating roll is brought into contact with a first end side of a doctor or back-up roll, is measured and stored as data in a memory. After starting, the amounts of movement of both ends of the rolls are controlled in driving of the doctor or back-up roll to be in contact with/separated from the coating roll so that the second end side of the roll is moved by a distance larger by the clearance size than the first end side of the roll on the basis of the clearance size data. Thus, the clearance size is corrected so that the outer peripheral surfaces of the rolls driven to be in contact with/separated from each other are continuously retained parallel in arbitrary moving positions.
