The invention relates to a method for producing a plastic film from a thermoplastic material in a film-production facility by extrusion out of a nozzle, the plastic or plastic melt of the nozzle beingsupplied by means of at least one extruder. The tubular film or web of film is then extruded from the nozzle and wound up by means of a winding device to form a film reel or a film coil. A referenceparameter is provided, and when the facility is in operation, at least two, preferably at least three input parameters different from the reference parameter are measured by means of measuring devices. An output parameter corresponding to the reference parameter is determined from said measured input parameters by means of at least one evaluation device. 一种用于在薄膜制造设备中通过从喷嘴中挤出由热塑性塑料制造塑料薄膜的方法，其中，借助于至少一个挤出机将塑料或塑料熔体输送给喷嘴，接着将薄膜软管或薄膜幅面从喷嘴中挤出并且借助于卷绕装置卷绕成薄膜卷或薄膜圈。提供基准参数，并且在设备的持续的运行中借助于测量装置来测量至少两个、优选至少三个不同于基准参数的输入参数。借助于至少一个评价装置由这些所测量的输入参数确定相应于基准参数的输出参数。
