Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a thermoplastic resin sheet which can improve the yield and quality of the sheet and a device for detecting a fault. SOLUTION: The thermoplastic resin sheet is produced by using an electrostatic application device having a cooling drum and electric discharge electrodes formed above the drum. In the method, when a fault is detected by the fault detecting device, a countermeasure means is instructed and monitored by the fault detecting device to adjust production conditions.
