Abstract

A method for transforming plastic preforms into plastic bottles, in which preforms are introduced into blowing stations, each blowing station having at least one blow mold and a stretching rod for stretching the preform along a longitudinal axis of the preform within the blow mold, and the preforms are expanded to form the plastic bottles by being acted upon by a gaseous medium in the blow mold, wherein a wall thickness of the plastic container is measured by at least one measuring device which outputs the measured values to a closed-loop and/or open-loop control device, wherein at least a stretching speed of the stretching rod is varied by the closed-loop and/or open-loop control device at least at times and/or at least in some locations during the blowing operation, individually for each blowing station, in order to adjust a wall thickness of the plastic bottles.
