Abstract: PROBLEM TO BE SOLVED: To solve the problem that, in a process for producing a thermoplastic resin film, when a drawing machine is stopped, the film in the vicinity of a heating machine is softened by the remaining heat of the heating machine and hangs down to contact the heating machine to cause fusion and firing, and especially when the drawing machine is stopped urgently for film quality, etc., the trouble is eminent. SOLUTION: In a heat insulating device for the drawing machine for the thermoplastic resin film, in a process for heat-stretching the film continuously, a plate is provided for insulating heat from a heater after the drawing machine is stopped.
