PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing a flexible ceramic sheet which can produce a long ceramic sheet by continuous firing. SOLUTION: When a longitudinal green sheet 12 placed on an endless belt 28 is continuously passed through a firing furnace 24 together with the endless belt 28, an entrance of the firing furnace 24 among the longitudinal green sheets 12 is provided. Since the slack T1 is always formed in the portion corresponding immediately before, In the longitudinal direction inside the firing furnace 24, the inlet side from the center, For example, at around 500 ° C. in the firing temperature profile, even if the unsintered sheet 12 shrinks due to the disappearance of the organic fibers or the reaction or melting of the inorganic binder, the tension is generated due to the slack T1. Is reduced or the unsintered sheet 1 is reduced by the shrinkage. 2 is moved toward the inside of the baking furnace 24 at a speed higher than the conveying speed of the endless belt 28, so that cracking and cutting of the ceramic sheet are preferably prevented. |
