METHOD FOR PRODUCING A PLASTIC FILM WITH A LOW THICKNESS TOLERANCE |
摘要 |
A method of producing a thermoplastic foil with reduced thickness tolerances in which close to the head the temperatures of the mass flow emerging from the heat at various regions corresponding to tempering sectors are detected, the temperature measurements are averaged and the averages are used to form a set point value with which the individual averages are compared and the comparison used to generate a correction signal which is applied to the temperature controller of the respective sector. |
