Abstract
The method and device are used to blow form containers. A preform is elongated by means of an elongation bar after thermal conditioning inside a blow mould and is moulded into a container under the effect of the blow pressure. Initially, a first blow pressure provided by a low pressure supply is used, followed by a higher pressure provided by a high pressure supply (). The blow air is supplied via at least one blow pressure valve and at least one part of the high pressure blow air is fed into the low pressure supply after the container has been formed. The reintroduction of blow air into the low pressure supply is controlled by means of a return valve () which is mounted parallel to the blow pressure valve. An outlet of the return valve is connected to the low pressure supply.
