The hollow bodies are made from thermoplastics by blow-moulding, and extruded through a nozzle as hoses or pipes. The ejector unit is mounted on the movable mould-carriage and travels between reception and ejection stations. Their movements are interlinked, so that with the movement of the carriage to the extrusion nozzle, the ejector travels in the opposite direction away from the carriage to the ejection station. |
