Abstract: The present invention relates to an apparatus for producing inline stretched tubular foils by the blowing process, having a blown foil system comprising an extruder, a blowing head, a cooling ring, a calibrating basket, a flat laying unit and a reversing turret haul-off, having a stretching system for monoaxially stretching the laid flat foil in the machine direction and with a first thinness control system which operates segmented control zones in the cooling ring to form thinness sections so that, during stretching, a foil is produced with a thickness profile having the smallest possible deviations from the medium foil thickness over the complete foil width. To increase the accuracy and speed of the first thinness section control system, a second thinness section control system is provided which controls two opposing heat sources between the calibrating basket and the flat laying unit and which can be connected to the first thinness section control system.

Abstract: An operator control device for operating a plurality of functions, in particular, in a vehicle, has at least a first rotary actuator and a second rotary actuator. A respective rotary actuator is assigned a function of the vehicle. The first rotary actuator has a first rotary body and a first operator control body, where the first operator control body is mechanically coupled with the first rotary body. The second rotary actuator has a second rotary body and a second operator control body, where the second operator control body is mechanically coupled with the second rotary body. The first rotary body and the second rotary body are arranged coaxially in each other such that they can be rotated about a common axis of rotation. At least one operator control body has a grip area that is designed in a lever-like manner.
