Abstract
The device is used for the blow-molding of containers. A preform made of thermoplastic material, following a thermal conditioning within a blow-mold, is stretched by a stretching rod and is reshaped by effects of blowing pressure into the form of a container. A specification for the positioning of the stretching rod occurs through the use of a linear drive. Blowing pressure is created through the use of at least one positionable blowing gas supply. The linear drive is at least intermittently mechanically coupled with the positionable blowing gas supply and the stretching rod in such a way that coordinated movement kinetics are carried out. The coupling means and the coupled elements are constructed in such a manner that the axis of motion and the resulting force-effect axis form a common spatial axis.
