Abstract

The invention relates to a method and a device for blow-molding containers. Following a thermal conditioning process, a parison is stretched by a horizontal bar inside a blow station provided with a blow mold, and is molded into a container by the effect of the blowing pressure. In order to carry out the blow-molding, pressurized gas is introduced into the container. The horizontal rod is hollow at least in parts. Once a maximum blowing pressure has been reached in the blow station and at the earliest at the beginning of a pressure drop, a cooling gas is guided out of the horizontal bar towards the bottom of the blown container.
