Abstract
The invention relates to a method and a device for blow-molding containers. Following thermal conditioning inside a blow-mold of a blow-molding machine, a preform (1) is formed into the container (2) by means of blowing pressure. The necessary blow-molding gas (P1, P2) is provided by a supply device. The stored, pneumatic pressure energy inside the blown container is at least partially transformed into another form of energy.
Claims18
A method for blow-molding containers, comprising the steps of:
- shaping a preform, after a thermal conditioning, into a container within a blow-mold of a blow-molding machine by influence of blowing pressure;
- providing blowing gas from a supply device;
- and transforming at least a portion of pneumatic pressure energy stored within the blow-molding container into another type of energy, including carrying out at least a portion of the energy transformation with a cam control.
An apparatus for-blow molding containers, comprising:
- at least one blow-molding station with a blow-mold;
- a pneumatic supply device connected to the blow-molding station;
- and a transformation device, the blow-molding station being coupled to the transformation device so that at least a portion of pneumatic pressure energy stored within the blow-molded container is transformable into another type of energy, wherein the transformation device is coupled to a cam control.
