Claim 0:
1. A method for controlling a thickness profile of a film track along a transverse direction by a plurality of adjusting actuators for adjusting a slot opening of a discharge nozzle of the flat film machine, comprising:
acquiring a thickness profile along the transverse direction of the film track transverse to a production direction of the flat film machine,
comparing at least a partial section of the acquired thickness profile with a preset profile,
determining at least one local profile deviation in a deviation section as a result of the comparison,
using a controlling device for generating at least one controlling intervention for the adjustment of at least one of the plurality of adjusting actuators in an intervention section different from the deviation section;
wherein the controlling device takes into account a temporally preceding controlling intervention when generating the controlling intervention.
