Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoplastic resin sheet using a static electricity applying casting method, drastically increasing the upper limit of a sheet molding speed caused by the applying irregularity defect generated in the thermoplastic resin sheet, and a static electricity applying casting method used therein. SOLUTION: In the method for manufacturing the thermoplastic resin sheet using the static electricity applying casting method when a thermoplastic resin is melted and extruded from a cap in a sheetlike state and the extrudate is cooled and solidified by a cooling drum, electrostatic charge is applied to the thermoplastic resin extruded into a sheetlike shape in a molten state so that the generation quantity of electrostatic charge in the vicinity of the end edge part of the sheet is made less than that of the central part of the sheet and a position where the generation quantity of electrostatic charge becomes little is made adjustable in the width direction of the sheet.

Abstract: PROBLEM TO BE SOLVED: To improve quality of a sheet-like article by using a thickness meter for measuring the thickness in the width direction also for measuring the thickness in the longitudinal direction without generating any trouble to measure the thickness in both directions. SOLUTION: In a method for preparing a sheet-like article wherein a resin is extruded into the sheet-like article from a nozzle and wound after molding, movement of a thickness meter provided between the nozzle 1 and a winding machine 11 and moving in the width direction of the sheet-like article is stopped based on a signal from other processes and the thickness in the longitudinal direction of a sheet-like article is measured at the stopping position.

Abstract: PROBLEM TO BE SOLVED: To make it possible to produce a plastic sheet-like material with which high productivity is obtainable by executing a state for drying a coating material by using dry air after a coating stage. SOLUTION: A coating material is applied on at least one surface of the plastic sheet-like material in succession to longitudinal stretching and is set to a transversely stretching machine, for example, a tenter. The coating material is dried by using air in the transversely stretching machine and the coated plastic sheet-like material is heated up the target transversely stretching conditions. In this drying stage, the plastic sheet-like material is heated up to the transversely stretching conditions by using the dehumidified air, by which the drying of the coating material is accelerated and the production of the plastic sheet-like material at a production rate higher than heretofore is made possible without changing the air temp., wind rate and the coating thickness of the coating material which are the conditions exclusive of humidity. The production is made possible without the occurrence of the unequal application and application defect of the coating material by the improvement in dryability.

Abstract: PROBLEM TO BE SOLVED: To accurately regulate a slit gap of a mouthpiece even when a twist occur due to application of rotary torque to a driving shaft for coupling the head to a motor by outputting a correction of an operating amount of the motor corresponding to a measured twist amount of the shaft. SOLUTION: A motor controller 31 calculates a torque applied to a driving shaft 21 by a load of a motor. A thickness is accurately regulated without influence of a twist of the shaft 21 without using a unit for measuring the twist of the shaft 21 by calculating the twist amount of the shaft 21 by the calculated torque applied to the shaft 21, and giving an operating amount corresponding to the twist amount of the shaft 21 to the motor 23 and hence outputting a correction of the operating amount corresponding to the twist amount. And, a current value of the motor is measured by a measuring instrument 32, and a load of the motor 23 can be measured without using a complicated unit.

Abstract: PROBLEM TO BE SOLVED: To produce a resin film excellent in thickness accuracy over the total width of a cap. SOLUTION: In a resin film producing line, the slit gap adjusting bolt 12 provided to a cap 1 emitting a thermoplastic resin is connected to a drive motor 23. The drive motor 23 is operated by the command value from a motor control unit 31 and the command value is operated by taking the thickness irregularity data in the width direction of the film measured by a motor controlled thickness meter 33 in an operation part 30. The rotary direction and quantity of rotation of the drive motor 23 are controlled on the basis of the command value of the motor control unit 31.
