<p>PROBLEM TO BE SOLVED: To provide a method for producing a sheet capable of drastically reducing loss just after the start of production of the sheet, by producing the sheet having a profile having a target thickness from just after discharge of a molten material. SOLUTION: The mouthpiece is provided in a producing device of the sheet and is heated by a heater. Thereafter, a gap just before discharge of a molten material is measured and the sheet of the profile having the target thickness is produced by regulating the measured gap to a target. Furthermore, in order to measure the slit gap profile, the device for measuring the slip gap profile is fitted to the body of the mouthpiece and equipped.</p> |
