Abstract

Nozzle head for appts. for blow moulding hollow bodies has a capillary tube having one end connected in a gas-tight manner with a connecting piece, and the other end extending at least into the blowing nozzle of the blowing mandrel. The connecting piece is fastened detachably to the gas outlet of the blowing mandrel body. The position of the outlet and of the capillary tube can be easily placed in a desired position by bending. Enables cooled, liquefied gases to be accurately supplied.
