Abstract
A blowing apparatus for expanding containers with a gaseous medium has a blowing piston and a blowing nozzle, through which the container is expanded with the gaseous medium. The blowing piston is movable in a longitudinal direction (L) of the blowing nozzle, the blowing nozzle is movable in the longitudinal direction (L) relative to the blowing piston, and a guide device is provided which guides the movement of the blowing nozzle in the longitudinal direction (L) relative to the blowing piston.
Claims19
A method for expanding containers with a gaseous medium, comprising the steps:
- lowering a blowing piston, which has a blowing nozzle arranged on the blowing piston such that it can be moved in a longitudinal direction (L) of the container, in the longitudinal direction of the container as far as a predefined end position of the blowing piston relative to the container;
- filling the container with the gaseous medium through the blowing nozzle;
- wherein the guide device has an inner wall which surrounds a mouth of the container during the blowing process.
A blowing apparatus for expanding containers with a gaseous medium, comprising a blowing piston and a blowing nozzle, through which the container is expanded with the gaseous medium, wherein the blowing piston is moveable in a longitudinal direction (L) of the blowing nozzle, the blowing nozzle is moveable in the longitudinal direction (L) relative the blowing piston, and a guide device is provided which guides the movement of the blowing nozzle in the longitudinal direction (L) relative to the blowing piston, wherein the guide device has an inner wall which surrounds a mouth of the container during the blowing process.
A blowing apparatus for expanding containers with a gaseous medium, comprising a blowing piston and a blowing nozzle through which the container is expanded with the gaseous medium, wherein the blowing piston is movable in a longitudinal direction (L) of the blowing nozzle, the blowing nozzle is movable in the longitudinal direction (L) relative to the blowing piston, and a guide device is provided which guides the movement of the blowing nozzle in the longitudinal direction (L) relative to the blowing piston, wherein the blowing nozzle is secured relative to the guide device using a screw body which surrounds the blowing nozzle in the circumferential direction.
